What do copper and nickel make?
Copper-nickel or copper-nickel (CuNi) is an alloy of copper and nickel, and usually a small amount of other metals, such as iron and manganese, are added to enhance its strength. The copper content is usually between 60% and 90%. Monel is a nickel-copper alloy containing at least 52% nickel.
