C71500 Copper Nickel '70/30' (CDA 715)
C71500 Copper Nickel is a high-strength, high-nickel content copper alloy with outstanding corrosion resistance in seawater and excellent thermal and electrical conductivity, widely used in marine applications including heat exchangers, condenser tubes, and various components in naval engineering.
Standards: ASTM B-151. ASTM B-122. DIN 2.0882
C70600 & C71500. 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.
