CuNi2 / CuNi6 / CuNi8 / CuNi10 Copper Nickel CuNi Alloy Electric Heating Wire With Low Resistance

CuNi2/CuNi6/CuNi8/CuNi10 Copper Nickel CuNi Alloy electric heating wire with Low Resistance

Copper nickel wire refers to a type of alloy wire composed primarily of copper and nickel. It is commonly used in various applications due to its unique properties, such as corrosion resistance, high electrical conductivity, and thermal stability. The ratio of copper to nickel in the alloy can vary, but the most common compositions are 90/10 and 70/30, indicating the percentage of copper and nickel, respectively.

The 90/10 copper nickel alloy wire contains 90% copper and 10% nickel. It is known for its excellent resistance to seawater corrosion, making it suitable for marine and offshore applications. This alloy is widely used in industries such as shipbuilding, desalination plants, power generation, and hydraulic systems.

The 70/30 copper nickel alloy wire contains 70% copper and 30% nickel. It offers a balance between corrosion resistance and mechanical strength. This alloy is commonly used in applications that require resistance to both corrosion and biofouling, such as heat exchangers, condensers, and offshore structures.

Copper nickel wire is available in different diameters and forms, including round wire, flat wire, and stranded wire, to suit specific requirements. It can be easily fabricated, welded, and soldered, making it a versatile material in various industries.
