Product Description
ASTM B111 C68700 Copper Steel Tube In Cooling Systems
Product Description
The ASTM B111 C68700 copper alloy steel heat exchanger tube is a seamless tube made from a copper-nickel alloy (70% Cu, 30% Ni). This alloy is specifically engineered for heat exchangers, condensers, and cooling systems requiring exceptional corrosion resistance (particularly in seawater), combined with high strength and thermal conductivity.
The C68700 copper-nickel alloy delivers superior performance in marine, chemical, petrochemical, and power generation applications where heat exchange systems face harsh environments including saltwater, brines, and corrosive fluids. The tube offers excellent resistance to stress corrosion cracking and maintains robust mechanical strength, ensuring long-term durability in demanding operational conditions.
