CuNi Alloy CuNi10 NC015 2.0811 C70700 Low Resistance Heating Alloy Wire for Diverse Applications in Modern Engineering and Technology

CuNi10 is a copper-nickel alloy containing 90% copper and 10% nickel, with small amounts of iron and manganese to enhance its properties. Known for its excellent corrosion resistance, particularly in marine environments, it is widely used in seawater systems and applications requiring durability in harsh conditions. The alloy resists biofouling, stress corrosion, and erosion, making it highly reliable in demanding environments.

CuNi10 offers good mechanical strength and ductility, facilitating fabrication into pipes, fittings, and other components. It also exhibits high thermal conductivity, making it suitable for heat exchangers and condensers, particularly in power plants, desalination systems, and chemical industries. Its moderate electrical conductivity allows its use in specific electrical applications, such as resistance wires and connectors.

Key applications include marine piping, shipbuilding, heat exchangers, and condensers, as well as architectural cladding and roofing in coastal areas. It is also used in coinage for its wear resistance and aesthetic qualities. CuNi10 is favored in industries such as marine engineering, power generation, petrochemicals, and electronics due to its combination of corrosion resistance, strength, and thermal conductivity. This makes it an ideal choice for components exposed to seawater, aggressive chemicals, or high-temperature environments.
