ASTM B111 / ASME SB111 C71500 CuNi30Mn1Fe Copper Alloy Seamless Tube for Condenser
TONG CHUANG GROUP supply kinds of copper alloy tubes containing C44300， C68700， C71500， C70600， C12200， etc. Tubes in a variety of sizes widely used for marine applications， condenser， heater， equipment， etc. C71500 (CuNi 70/30) ， Copper nickel offers excellent corrosion resistance， especially in marine salt water environments. The main， wrought copper-nickel alloys chosen for sea water service contain 10 or 30 percent nickel. They also have important additions of iron and manganese which are necessary to maintain good corrosion resistance. Some common applications for copper nickel include: valves， and pump components.
