Cupronickel

Cupronickel

Cupronickel (also known as copper-nickel and CuNi) is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. Despite its high copper content, cupronickel is silver in colour

Due to the specific properties of nickel and copper alloys, they are applied in various domains of industry e.g. coin and medal minting, armaments manufacture, desalination materials, marine engineering, and extensively used in the chemical, petrochemical and electrical industries

Cupronickel is highly resistant to corrosion in seawater. For this reason, it is used for piping, heat exchangers and condensers in seawater systems, marine hardware, and sometimes for the propellers, crankshafts and hulls of superyachts, premium tugboats, fishing boats and other working boats
