Description

CuNi10 NC015 2.0811 C70700 CuNi Alloy Copper-Nickel Alloy Wire for Marine Environments Heat Exchangers and Electrical Systems

CuNi10 is a copper-nickel alloy containing approximately 90% copper and 10% nickel, known for its exceptional resistance to corrosion, particularly in seawater environments. It also offers good strength, ductility, and high thermal conductivity, making it ideal for a variety of demanding applications. The alloy is commonly used in marine engineering, power generation, and chemical industries, where its resistance to both seawater corrosion and biofouling is highly valued.

In marine applications, CuNi10 is employed in seawater piping systems, heat exchangers, condenser tubes, and shipbuilding components, as it is highly resistant to corrosion and fouling. It is also used in chemical processing, particularly in equipment exposed to aggressive chemicals and high temperatures.

Additionally, CuNi10 is used in heat exchangers in power plants and desalination facilities, owing to its ability to perform reliably in harsh environments. In coinage, its durability and aesthetic qualities make it a popular choice for producing corrosion-resistant coins.

This alloy also finds use in electronics for connectors and resistors due to its moderate electrical conductivity and mechanical strength. CuNi10’s combination of corrosion resistance, strength, and workability makes it a versatile material in industries where durability and longevity are essential.
