Aluminium Extrusion Scrap & UBC Scrap: A Growing Export Market Driven by India

Global aluminium scrap trade is increasingly shaped by countries where downstream consumption is large, stable, and long term. Among these, India has emerged as one of the most consistent destinations for aluminium extrusion scrap and UBC (Used Beverage Can) scrap. For recyclers, scrap yards, demolition contractors, and trading companies, India represents a market that absorbs volume year after year rather than reacting only to short-term price cycles.

This article is written for sellers who generate aluminium scrap on a regular basis and are evaluating where sustained export demand exists.

Understanding the material in demand

Aluminium extrusion scrap includes production offcuts from extrusion plants, industrial profile scrap, and post-construction material such as window frames, doors, curtain wall sections, channels, and angles. Much of this material originates from manufacturing inefficiencies, renovation activity, or industrial dismantling.

UBC scrap, on the other hand, consists of used aluminium beverage cans. It is one of the most standardized aluminium scrap grades globally because of its relatively predictable chemistry and melting behavior. As beverage consumption grows worldwide, UBC continues to remain a core feedstock for secondary aluminium producers.

Indian buyers typically focus on material that is reasonably sorted, commercially practical to melt, and available with consistency rather than perfect one-off parcels.

Countries already exporting aluminium extrusion scrap and UBC

A number of regions already have mature aluminium scrap export ecosystems and actively ship to India. These include the United States, Canada, Mexico, the United Kingdom, Germany, the Netherlands, Belgium, France, Italy, Spain, Poland, the United Arab Emirates, Saudi Arabia, Oman, Japan, South Korea, Malaysia, Thailand, Indonesia, Singapore, Australia, and South Africa.

These countries benefit from established recycling networks, steady industrial scrap generation, reliable port infrastructure, and familiarity with international shipment procedures. For many sellers in these regions, exporting aluminium scrap is already a routine extension of their domestic recycling activity.

Emerging opportunities for new exporting regions

Beyond traditional exporters, several regions are gradually becoming relevant sources of aluminium scrap for the international market. Southeast Asian countries such as Vietnam and the Philippines are seeing increasing scrap generation as manufacturing activity expands. Parts of Eastern Europe and the Balkans, including Romania, Bulgaria, and Serbia, are strengthening collection and export capabilities.

Mediterranean markets such as Turkey and Greece, as well as select African countries like Egypt and Kenya, are also seeing growing aluminium usage and recycling volumes. For sellers in these regions, India often becomes attractive when local consumption is limited or pricing fluctuates.

Why India imports large volumes of aluminium scrap

India’s reliance on imported Aluminium scrap is structural rather than temporary. Downstream industries such as construction, power transmission, automotive components, packaging, and general engineering consume large quantities of Aluminium on a continuous basis.

Secondary aluminium production is significantly more energy efficient than primary smelting, which makes scrap-based operations economically attractive. While India generates domestic scrap, collection efficiency, segregation quality, and regional availability vary widely. Imports help stabilize supply and allow plants to run at consistent capacity.

Indian smelters and casters also prefer predictable feedstock flows, making regular import streams an integral part of their procurement strategy.

How experienced sellers usually position their material

In practice, exporters who develop repeat business into India tend to follow a market-led approach. Rather than focusing on isolated shipments, they present their material in a manner that supports transparency, continuity, and long-term planning.

Sellers who move volumes smoothly generally have clear internal visibility on the condition of their stock, realistic monthly generation ranges, preferred loading ports, and general grade characteristics. Commercial discussions are typically framed around workable references such as FOB or CIF levels rather than fixed spot expectations.

This clarity reduces friction in negotiations and allows discussions to progress toward sustainable trade structures. Over time, Indian buyers naturally gravitate toward suppliers who can offer regular availability and commercial adaptability, as these align more closely with plant operating cycles than one-time parcels.

Managing risk and avoiding fraud in cross-border scrap trade

International scrap trade requires discipline on both sides. Professional transactions are built around verification, documentation, and structured commercial terms. Material inspections, shipment documentation, and counterparty checks form part of standard operating practice.

By aligning payment timelines with material movement and downstream consumption cycles, both sellers and buyers are able to reduce exposure and avoid misunderstandings. This structured approach supports trust development over multiple shipments rather than relying on assumptions in the first transaction.

A long-term market rather than a one-off destination

For scrap generators and traders with ongoing aluminiumextrusion scrap or UBC availability, India offers more than short-term price arbitrage. It offers depth, continuity, and the potential for stable offtake over extended periods.

Protective Plastic Coating with Aluminum Silver Paste

Protective plastic coating with aluminum silver paste is a plastic coating material that incorporates aluminum silver paste as a functional additive, providing a unique metallic texture and excellent protective properties. Here’s a detailed explanation:

Key Characteristics

Excellent Optical Effect: The aluminum powder within the aluminum silver paste possesses high reflectivity, enabling the coating to exhibit a captivating silver luster and metallic texture. It also offers good hiding power and high brightness, significantly enhancing the visual appeal of plastic products.

Good Aging and Corrosion Resistance: Specially processed aluminum silver paste demonstrates strong resistance to aging and corrosion. It can withstand the erosion of external environmental factors such as ultraviolet light, acid and alkali corrosion, and thermal aging, thereby extending the service life of the coating and the plastic substrate and maintaining the coating’s long-term aesthetic appeal.

Anti-Corrosion and Shielding Properties: The overlapping arrangement of aluminum flakes creates an effective barrier on the material surface, giving the coating anti-corrosion properties. This prevents harmful substances from penetrating and protects the plastic substrate from environmental corrosion.

Good Compatibility and Processability: Aluminum silver paste is compatible with various plastic materials. It can disperse evenly on the plastic substrate, forming a uniform and smooth coating. Additionally, it possesses strong processability and can be shaped and coated through standard plastic manufacturing processes, simplifying production operations.

Wide Variety Based on Aluminum Silver Paste Dispersion Characteristics:

We categorize aluminum silver pastes into floating and non-floating types. Floating aluminum silver paste, where the aluminum flake surface absorbs saturated fatty acids, exhibits hydrophobicity and oleophilicity. During coating, it floats on the coating surface, providing high reflectivity and a soft chrome-like effect. However, the surface aluminum flakes are prone to oxidation, blackening, and flaking, making it less recommended for alkaline environments like building exteriors. Non-floating aluminum silver paste can be completely wetted by the coating, adhering uniformly throughout the coating. It emphasizes downward movement. The aluminum flakes’ particle size and particle size distribution determine many properties, including covering power and tinting strength. The paint film is uniform and firm, allows for recoating and polishing, and has many applications.

Classification Based on Aluminum Silver Paste Appearance:

Varieties include electroplating silver effect, sparkling silver, and fine platinum. The electroplating silver effect has a particle size and color between fine platinum and sparkling silver. It can display a satin metallic texture and a metallic effect similar to chrome plating, suitable for high-end plastics, automotive parts, and artistic spraying. Sparkling silver has a larger average particle size, higher brightness, good water permeability, good reliability, good particle size, and excellent sparkling and metallic effects, making it suitable for industrial decoration and automotive coatings. Fine platinum has the smallest average particle size and lower brightness than electroplating silver, but it offers good hiding power and provides excellent tinting strength and an elegant metallic effect; widely used in general industrial paints, coil coatings, marine paints, anti-corrosion coatings, and 3C digital coatings.

Scope of Application

Automotive Field: We use it to paint car bodies and wheel hubs, make the vehicle surface delicate and beautiful, and enhance the car’s quality and grade. Its wear and aging resistance protects the car’s coating and extends its service life.

Home Appliance Field: As an additive to plastic masterbatches for plastic components like home appliance housings, it provides a metallic texture and pattern, improving the product’s appearance, quality and market competitiveness.

Construction Field: It is suitable for exterior wall coatings and metal roof coatings.

How Does Aluminum Silver Paste Impart Metallic Luster in Plastic Coatings?

Aluminum silver paste imparts metallic luster in protective plastic coatings through the following mechanisms:

Reflecting Light Sources: The aluminum flakes within the aluminum silver paste possess high reflectivity, enabling them to reflect light sources, including visible light and some invisible light, like a mirror. When light strikes the aluminum flakes on the coating surface, a significant portion reflects, causing the coating to exhibit a luster similar to the reflected light from a metal surface. This reflection is the primary mechanism by which aluminum silver paste imparts a metallic texture to the coating.

Scattering Light: The irregular shape and arrangement of the aluminum flakes cause light to scatter. When light encounters the aluminum flakes, in addition to reflection, scattering occurs on and around the flake surfaces, causing light to propagate in different directions. This scattering enhances the coating’s gloss and makes it appear more three-dimensional and layered, similar to the luster change of a metal surface under different viewing angles.

Covering Substrate Color: Aluminum silver paste has good hiding power and can effectively cover the color and surface defects of the substrate. Adding an appropriate amount of aluminum silver paste to the coating allows the coating surface to exhibit a uniform silvery-white metallic luster, reducing the impact of the substrate color on the coating’s appearance and making the overall coating look smoother, more beautiful, and closer to the appearance of metal.

Providing a Smooth Surface: Aluminum silver paste forms a relatively smooth surface in the coating, which is conducive to light reflection and scattering. The arrangement and distribution of aluminum flakes make the coating surface smoother and more uniform, reducing the scattering loss of light on rough surfaces and enhancing the coating’s gloss. This smooth surface effect resembles polished metal’s soft and lustrous surface.

Interaction of Optical Properties with the Coating: Aluminum silver paste interacts with other components of the plastic coating, creating a coating system with specific optical properties. The optical properties of the aluminum flakes (such as transmittance and refractive index) combine with the optical properties of the plastic substrate, causing the coating to exhibit a unique metallic texture and visual impact under certain light conditions. This interaction allows the aluminum silver paste to impart metallic luster in plastic coatings efficiently and harmonize with many properties of the coating (such as anti-aging and anti-corrosion) to enhance the overall performance of the coating.

We at Five New Materials are proud to offer aluminum silver pastes that empower protective plastic coatings with these remarkable properties. Our materials are designed to meet the demanding needs of industries seeking aesthetic appeal and robust protection.

In this blog, we will explore the fascinating world of ALC, from its production to its applications, and delve into how our aluminum paste contributes to its outstanding characteristics. Join us as we uncover the potential of ALC and our products’ essential role in shaping sustainable construction’s future.

At Five Star New Materials, we supply high-performance aluminum paste, a crucial ingredient that empowers the production of Autoclaved Lightweight Concrete (ALC). ALC stands as a revolutionary building material, shaping the future of construction with its exceptional properties. We are proud to provide the essential component that helps make ALC possible.

Understanding Autoclaved Lightweight Concrete (ALC)

Manufacturers produce Autoclaved Lightweight Concrete by combining carefully selected raw materials, including fly ash (or silica sand), cement, and lime. Crucially, they incorporate our aluminum paste as the vital aeration agent.

The production process involves proportioning these materials, mixing, pouring, pre-curing, cutting, and finally, autoclaving (steam-curing under pressure). This sophisticated process yields a unique concrete product.

ALC is a porous concrete panel characterized by numerous delicate, evenly distributed pores. Our aluminum paste reacts with alkaline components in the mix during production to generate hydrogen gas. This reaction creates these essential pores, achieving a 60-70% porosity. This controlled structure is the key to ALC’s outstanding performance characteristics.

The Advantages Enabled by High-Quality Aeration

The porous structure, facilitated by our aluminum paste, gives Autoclaved Lightweight Concrete its remarkable properties:

Lightweight and High Strength

ALC achieves impressive strength despite its low density. For example, Grade 05 ALC panels typically have a density of around 525 kg/m³ yet offer a compressive strength of ≥4 MPa. This density is approximately one-quarter that of traditional concrete and one-third that of clay bricks. This significantly reduces a building’s dead load, leading to savings in foundation and structural costs.

Superior Thermal Insulation

The entrapped air pores minimize thermal conductivity. Grade 05 ALC typically exhibits a thermal conductivity of ≤0.14 W/(m·K). This provides insulation performance far superior to traditional materials – approximately six times better than glass, three times better than clay brick, and ten times better than standard concrete. This enhances indoor comfort and significantly reduces building energy consumption for heating and cooling.

Excellent Fire Resistance

As an inorganic material, ALC does not burn. Critically, it does not release harmful gases when exposed to high temperatures. Autoclaved Lightweight Concrete wall panels can achieve fire resistance ratings exceeding 4 hours, making them ideal for firewalls and escape routes.

Effective Sound Absorption and Insulation

The porous nature effectively absorbs sound waves. Depending on the thickness and density, ALC panels can reduce noise transmission by 30-50 decibels, contributing to quieter and more comfortable indoor environments.

Enhanced Seismic Performance

The material’s porous structure effectively absorbs and disperses seismic energy. Using ALC improves building safety and reliability, particularly in earthquake-prone regions.

Efficient and Clean Construction

Manufacturers can prefabricate ALC panels to precise dimensions in a factory setting. Workers can easily cut, drill, mill, and nail the panels on site. This accelerates the construction schedule, reduces wet trades on site, and contributes to a cleaner, more environmentally friendly building process.

Eco-Friendly Material

ALC production generates minimal pollution and does not release harmful substances. Manufacturers can utilize industrial byproducts like fly ash as a primary raw material, aligning with green building principles and sustainability goals.

Common ALC Panel Dimensions and Applications

ALC panels offer versatility for various construction needs:

Length: Typically customized based on floor height, available up to 6 meters.

Width: Common widths include 600mm and 1200mm.

Thickness: A wide range is available, such as 100mm, 150mm, and 200mm, selected based on design requirements.

Builders utilize Autoclaved Lightweight Concrete extensively for:

Exterior Walls: Provides thermal insulation, durability, and reduced weight for residential, commercial, and industrial buildings.

Interior Walls: Offers excellent sound insulation and fire resistance for partitions, simplifying construction and maximizing usable space.

Floors: Suitable for floor systems in low-rise residential buildings, providing good acoustic and fire performance while reducing structural load.

Roofs: Serves as structural decking and insulation layers, offering weather resistance and thermal efficiency.

Fire Protection: Used for firewalls, shaft enclosures, and protection for steel structures due to its high fire rating.

Decorative Elements: These can be surface-treated as an attractive and durable façade or interior finish.

The Five Star Advantage: Premium Aluminum Paste for ALC

Our aluminum paste is specifically engineered for the Autoclaved Lightweight Concrete industry. It performs critical functions:

Precise Aeration: Our paste reacts predictably and efficiently with alkaline materials in the ALC mix, releasing hydrogen gas at a controlled rate. This creates the essential lightweight, uniformly porous structure.

Enhancing Performance: The consistent, fine pores generated by Five Star’s aluminum paste directly contribute to ALC’s superior thermal insulation, sound absorption, and fire resistance properties.

Optimizing Material Properties: By facilitating a controlled pore structure, our aluminum paste helps ALC manufacturers reliably achieve the target balance between low density and high compressive strength.

Why Particle Size Distribution Matters

At Five Star New Materials, we meticulously control the particle size and distribution of our aluminum paste because it directly impacts the final Autoclaved Lightweight Concrete quality:

Optical Properties (Internal Structure): While less critical for ALC than coatings, finer particles offer a larger surface area for reaction. A narrow, consistent particle size distribution ensures uniform pore formation, leading to predictable density, strength, and thermal performance in the final ALC product. Uneven distribution can lead to variations in pore size and structure.

Processing Performance: Filling & Density: A well-controlled particle distribution helps ensure the aeration process is uniform throughout the mix, contributing to a homogenous final product density and structure.

Durability Link: A uniform pore structure, initiated by consistent aluminum particles, contributes to the ALC’s overall integrity and long-term durability.

Application Performance:Dispersion: Our aluminum paste disperses easily and evenly within the ALC slurry. A narrow distribution minimizes settling variations, preventing inconsistencies and ensuring the stability and homogeneity of the mix before curing.

Reactivity Control: Optimized particle size allows for predictable and manageable reaction rates during the gas generation phase, which is crucial for controlling the rise and initial set of the ALC mixture.

Best Practices for ALC Construction

To maximize the benefits of Autoclaved Lightweight Concrete enabled by our quality aluminum paste, contractors should observe proper handling and installation techniques:

Moisture Protection: While ALC possesses some moisture resistance, designers must specify appropriate waterproofing membranes or coatings in areas prone to prolonged dampness or water exposure, such as bathrooms and kitchens.

Installation Accuracy: Ensure panels are installed level and plumb. Precise installation, especially for exterior walls, affects the building’s appearance, watertightness, and overall safety. Seal joints meticulously according to manufacturer recommendations to prevent air or water leakage.

Secure Anchoring: Follow structural engineering designs and relevant codes meticulously when anchoring ALC panels to the primary building structure. Proper anchoring guarantees stability, especially in multi-story buildings or areas with high seismic activity.

Impact Prevention: Although ALC is robust, avoid subjecting panels to sharp impacts or heavy point loads during construction and occupancy. If damage occurs, repair or replace the affected sections promptly to maintain the integrity and performance of the element.

Aluminum Paste Slurry: Specifically used in AAC production as a foaming agent, this slurry contains aluminum powder and additives mixed into a paste form to release hydrogen gas, forming a porous structure.

Function of Aluminum Paste Slurry in AAC Production

Foaming Mechanism: When aluminum paste slurry reacts with water in an alkaline slurry, it generates hydrogen gas, forming an even pore structure.

2𝐴𝑙+3𝐶𝑎(𝑂𝐻)2+6𝐻2𝑂→3𝐶𝑎𝑂⋅𝐴𝑙2𝑂3⋅6𝐻2𝑂+3𝐻2↑2Al+3Ca(OH)2​+6H2​O→3CaO⋅Al2​O3​⋅6H2​O+3H2​↑

Advantages of Aluminum Paste Slurry:

Safety: The use of oil—or water-based mediums eliminates the explosion risk present in dry grinding aluminum powder.

Ease of Use: The paste form makes it easier to measure and mix, reducing dust pollution and increasing production stability.

Cost Control: Using aluminum foil scraps reduces production costs.

Suitability of Aluminum Paste in AAC Production

Limitations: Aluminum paste is coated with a protective layer (such as stearic acid), which prevents water reactions and leads to insufficient foaming or failure. This makes it unsuitable as a substitute for aluminum paste slurry.

Potential Improvements: Chemically removing protective layers could reactivate the aluminum powder, though this process is complex and costly.

Future Development: The focus is on developing composite materials that combine foaming and decorative properties, but the balance between pore stability and aesthetic appearance must be maintained.

Autoclaved Aerated Concrete Blocks Aluminum Paste: Key Information and Benefits

Autoclaved Aerated Concrete (AAC) blocks aluminum paste is a key gas-generating material used in the production of Autoclaved Aerated Concrete. Through a chemical reaction, it forms a uniform pore structure within the concrete, granting the blocks characteristics such as light weight, thermal insulation, and heat resistance. Below is a detailed breakdown of its core information:

1. Mechanism of Aluminum Paste

Gas Generation and Porous Structure Formation The active aluminum powder in aluminum paste reacts with water in an alkaline environment, releasing hydrogen gas and forming a gel-like aluminum hydroxide. This process creates closed pores, significantly reducing the density of the blocks to 500-700 kg/m³, only one-fifth of ordinary concrete, while also enhancing thermal insulation properties.

Lightweight and Strength Improvement The porous structure reduces the weight of the blocks, cutting down building loads by over 40%. The even distribution of pores and the reasonable thickness of the pore walls ensure that the compressive strength can reach over 25 MPa, making Autoclaved Aerated Concrete blocks suitable for both load-bearing and non-load-bearing walls.

Improved Construction Performance The expansion of the slurry induced by the aluminum paste reaction makes the blocks easier to cut and process, reducing the amount of cement used and lowering production costs.

2. Aluminum Paste Production Process

Raw Material Treatment Aluminum ingots or aluminum foil scraps need to be screened to remove oxidation layers and ensure uniform granularity. When ball-milling, additives such as dispersants and corrosion inhibitors are used to enhance grinding efficiency and aluminum powder activity.

Ball Milling and Dehydration The materials are finely milled to a particle size of ≤0.075 mm using a specialized ball mill. The water is then removed using a dehydration press, resulting in aluminum paste, which is packed and stored.

Environmental Process Optimization Modern processes substitute traditional dry methods with tap or well water, reducing pollution and energy consumption. Some companies (like Baisheng Aluminum) utilize patented equipment to enhance efficiency, allowing for the dehydration and bagging of five machines per hour.

Soundproofing and Seismic Resistance: The internal pores absorb 41 dB of noise, and the lightweight structure reduces seismic inertia forces.

Waterproofing and Environmental Friendliness: The absorption rate is five times slower than clay bricks, and it utilizes industrial waste such as fly ash in its production.

Usage Considerations

Dosage Control: Excessive aluminum powder may cause overly large pores, reducing strength. The typical dosage is 0.4 kg/m³.

Dust Protection: Proper dust control measures are required during production to avoid harm from inhaling aluminum powder.

Comparing Autoclaved Aerated Concrete Blocks Aluminum Paste with Other Insulation Materials

Autoclaved Aerated Concrete (AAC) blocks aluminum paste has substantial advantages over other common insulation materials like EPS, rock wool, and ALC panels. Here’s a comparison analysis:

1. Lightweight and Structural Performance

Lightweight and Compressive Strength The dry density of Autoclaved Aerated Concrete blocks is 500-700 kg/m³, only one-fifth of regular concrete and one-third of clay bricks, significantly reducing building loads. Additionally, the compressive strength can reach 3.5-7.5 MPa, sufficient for both non-load-bearing and some load-bearing walls. In comparison, EPS and XPS, although lightweight, have lower strength and require composite structures. Rock wool panels have weak compressive performance and can deform when exposed to moisture.

Seismic Resistance The porous structure results in low seismic inertia. During the Tangshan earthquake, Autoclaved Aerated Concrete buildings only sustained minor cracks, while brick-concrete structures nearly collapsed. AAC blocks outperform traditional materials in seismic performance.

2. Thermal Insulation Performance

Low Thermal Conductivity With a thermal conductivity of 0.11-0.18 W/(m·K), a 20cm Autoclaved Aerated Concrete block wall provides the same insulation as a 49cm clay brick wall, far surpassing EPS (0.03-0.04 W/(m·K)) and rock wool (0.04-0.05 W/(m·K)).

Thermal Inertia and Adaptability High-density products can increase thermal inertia in the south, while low-density products reduce thermal conductivity in the north, adapting to different climates. Traditional insulation materials like EPS require additional thickness adjustments, adding complexity to construction.

3. Fire Resistance and Safety

Grade A Fire Resistance Autoclaved Aerated Concrete is an inorganic material with a fire resistance limit of over 3 hours, meeting national first-class fire resistance standards. EPS, on the other hand, is classified as B1/B2 and releases toxic gases when exposed to fire. Rock wool is also grade A, but it is more expensive.

No Risk of Cavities or Shedding Autoclaved Aerated Concrete blocks are monolithic, eliminating the need for external insulation layers and avoiding potential risks of detachment in composite systems like EPS, which require anchoring and may crack over time.

4. Environmental and Economic Benefits

Resource Recycling The materials used, such as fly ash and slag, account for over 75% of the raw materials, reducing solid waste and meeting green building standards. EPS relies on petrochemical products, and rock wool has high production energy consumption.

Lower Overall Cost The unit price of AAC blocks is around 145-200 RMB/m³, with wall construction costs approximately 75 RMB/m², lower than EPS exterior insulation systems (around 120 RMB/m²). While ALC panels offer fast construction, their material costs are 30%-40% higher.

5. Construction and Functionality

Ease of Construction Autoclaved Aerated Concrete blocks are easy to saw, nail, and plane, simplifying the process without complex columns and beams. In contrast, rock wool panels require special cutting tools, and EPS needs fireproof isolation strips, increasing construction difficulty.

Soundproofing and Water Resistance The internal pores of Autoclaved Aerated Concrete blocks absorb 41 dB of noise and have excellent water resistance, absorbing moisture five times slower than clay bricks. EPS has poor soundproofing, and rock wool’s performance decreases when exposed to water.
