#astmb111

The ASTM B111 C70400 tube is a high-performance copper-nickel alloy tubing widely used in condensers, heat exchangers, evaporators, and marine applications. This grade contains approximately 95% copper and 5% nickel, offering excellent corrosion resistance, especially in seawater and aggressive industrial environments. It also provides good thermal conductivity, durability, and resistance to pitting, erosion, and stress corrosion cracking.

ASTM B111 C28000 seamless tube is manufactured from a high-strength Muntz Metal (UNS C28000) copper-zinc alloy according to the ASTM B111 / ASME SB111 specification. Muntz Metal typically contains about 60 % copper and 40 % zinc, offering an excellent balance of strength, corrosion resistance, and cost-effectiveness compared with other brass materials.

The ASTM B111 C70600 is a seamless copper-nickel (90/10) alloy tube engineered for superior performance in corrosive and heat-transfer environments. Produced under the ASTM B111 specification, this tube is widely used in critical industrial sectors where resistance to seawater corrosion, biofouling, and thermal stress is essential.
