    CuNi2 is a copper-nickel alloy containing approximately 98% copper and 2% nickel, with small amounts of other elements like iron and manganese. This alloy is known for its excellent resistance to corrosion, especially in marine environments, making it ideal for applications exposed to seawater and other aggressive conditions. CuNi2 has moderate strength, good ductility, and outstanding resistance to biofouling, stress corrosion, and erosion, which enhances its durability in harsh environments.


    Common applications of CuNi2 include marine piping systems, heat exchangers, desalination plants, and marine hardware. It is also used in components like electrical connectors and resistive elements, benefiting from its corrosion resistance and moderate electrical conductivity. Additionally, CuNi2 is employed in shipbuilding, oil and gas industries, and architectural projects in coastal regions. The alloy’s properties of high thermal conductivity, combined with its resilience, make it a versatile and reliable choice in a variety of industrial and marine applications.
