#astmb466

ASTM B466 C70400 is a high-performance copper-nickel (Cu-Ni 95/5) seamless tube/pipe manufactured according to the ASTM B466 / ASME SB466 standard. This alloy consists of approximately 95 % copper and 4–6 % nickel, with trace iron and manganese — a combination that offers excellent resistance in marine, seawater, and corrosive environments.

ASTM B466 C72200 refers to high-quality Copper-Nickel Alloy 722 (C72200) seamless and welded pipe and tube manufactured to the ASTM B466 specification. Also known as Copper Nickel 72/28, C72200 offers an exceptional combination of corrosion resistance, strength, and thermal conductivity, making it highly suitable for marine, seawater, power generation, and industrial piping applications.

This alloy features approximately 72% copper and 28% nickel, along with small amounts of iron and manganese, which enhances its resistance to corrosion from seawater, chloride solutions, and various acidic environments. ASTM B466 C72200 tubing is widely used in heat exchangers, condenser tubes, cooling water systems, desalination plants, and offshore platforms where durability and long-term reliability are critical.

Emirerri Steel offers premium ASTM B466 C70600 copper-nickel seamless pipes and tubes, also known as UNS C70600 (90/10 Cu-Ni), engineered for demanding marine and industrial environments. Manufactured to strict ASTM B466 standards, this copper-nickel alloy features approximately 90% copper and 10% nickel with small additions of iron and manganese, giving it exceptional corrosion resistance in seawater and brackish water, high mechanical strength, and long service life.
