Copper Nickel 70-30 C71500 Up to 6 inches thickRequest a Quote C71500 material is recommended for use in pressure Vessels, condensers, and heat exchangers. It 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, pump components, fittings, flanges and various other marine hardware components. Typical Uses Some common applications for copper nickel include: valves, pump components, fittings, flanges and various other marine hardware components.
