Also known as Cu-Ni, it offers excellent corrosion resistance, especially in marine salt-water environments. Copper nickel alloys that are generally chosen for sea water parts and service equipments contain 10 to 30 percent nickel. Apart from being corrosion resistant to sea water, cupro nickel alloys are thermally stable. We provide cupro Nickle in various compositions and the main compositions that are demanded are 70:30, 95:05 and 90:10.
