Copper Nickel
Copper-Nickel is also called as Cupronickel, It is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. It is silver in colour.
Usage
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.
