Cupronickel (also known as copper-nickel) is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese.
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 premium tugboats, fishing boats and other working boats.
Characteristics of Copper Nickel Alloys:
• Excellent resistance to seawater corrosion
• Low macrofouling rates
• Good fabricability
• Good Tensile strength
Applications of Copper Nickel Alloys:
• Marine Engineering
• Cyrogenic applications
