thumb|Two stacks of Half dollar (United States coin)|Half dollars. The coins in the stack on the right are composed of copper with cupronickel cladding, and can be distinguished from the [[silver half dollars on the left by their visible copper cores.]] Cupronickel or copper–nickel (CuNi) is an alloy of copper with nickel, usually along with small quantities of other metals added for strength, such as iron and manganese. The copper content typically varies from 60 to 90 percent. (Monel is a nickel–copper alloy that contains a minimum of 52 percent nickel.)

thumb|Two stacks of Half dollar (United States coin)|Half dollars. The coins in the stack on the right are composed of copper with cupronickel cladding, and can be distinguished from the [[silver half dollars on the left by their visible copper cores.]] Cupronickel or copper–nickel (CuNi) is an alloy of copper with nickel, usually along with small quantities of other metals added for strength, such as iron and manganese. The copper content typically varies from 60 to 90 percent. (Monel is a nickel–copper alloy that contains a minimum of 52 percent nickel.)
Despite its high copper content, cupronickel is silver in colour. Cupronickel is highly resistant to corrosion by salt water, and is therefore used for piping, heat exchangers and condensers in seawater systems, as well as for marine hardware. It is sometimes used for the propellers, propeller shafts, and hulls of high-quality boats. Other uses include military equipment and chemical industry, petrochemical industry, and electrical industries.
