ASTM B111 C70600 Tube (UNS C70600), a 90/10 copper nickel tube offering excellent seawater corrosion resistance, thermal conductivity, and d
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.
Made from UNS C70600 (90% copper, 10% nickel) alloy, the tube offers excellent corrosion resistance in seawater and brackish water, high thermal conductivity for efficient heat exchange, and strong mechanical properties such as ductility and formability. It is available in various outside diameters (6 mm to 168.3 mm), wall thicknesses (0.7 mm to 10 mm), and lengths up to 6 meters, suitable for tailored engineering applications.
