Description

Copper Nickel Alloy CuNi4/NC007/C72150/2.0842 for Resistance Elements with Optimal Performance in Harsh Environments

CuNi4 is a copper-nickel alloy composed of approximately 96% copper and 4% nickel, with small amounts of iron and manganese. It is known for its excellent corrosion resistance, particularly in marine environments, as well as its resistance to biofouling, erosion, and stress corrosion cracking. CuNi4 also has good thermal conductivity, making it suitable for heat exchange applications, and moderate electrical conductivity, which allows it to be used in certain electrical components.

This alloy offers a good balance of strength and ductility, making it easy to fabricate into various shapes such as pipes, fittings, and structural components. It is commonly used in marine applications for seawater piping, shipbuilding, and marine hardware. Additionally, CuNi4 is employed in heat exchangers, desalination plants, electrical connectors, and even coinage due to its durability and resistance to corrosion. Its ease of fabrication, combined with its corrosion and thermal properties, make CuNi4 a versatile and reliable choice for a range of industrial and marine applications.
