Copper nickel (CuNi) offers excellent corrosion resistance especially in marine salt
water environments. Copper nickel alloys that are generally chosen for sea water
parts and service equipment contains 10 to 30 percent nickel. These various alloys
also have important additions of iron and manganese which are necessary to maintain
good corrosion resistance in the harsh environments. Aside from being very corrosion
resistant to sea water, copper nickel alloys are thermally very stable. Copper
nickel is most commonly used in applications such as electrical and electronic
products, tubes for condensers in ships and power plants, various marine products,
including valves, pumps, fittings and sheathing for ship hulls.
