Products Description

Copper-nickel wire is an alloy material composed of copper and nickel. It combines the excellent electrical conductivity of copper and the high corrosion resistance of nickel. This alloy is widely used in electrical engineering, shipbuilding, chemical equipment, and precision instruments due to its excellent physical and chemical properties. There are various grades of copper-nickel wire, such as CuNi1, CuNi2, CuNi10, CuNi44, etc. Each grade has its specific nickel content and corresponding performance characteristics to meet the needs of different application scenarios. In addition, special grades such as 6J8, 6J11, 6J13, etc., due to their unique alloy composition, are usually used to manufacture parts with special requirements for corrosion resistance, mechanical strength or thermal stability. The parameters of copper-nickel wire, including electrical conductivity, thermal conductivity, hardness and tensile strength, will vary depending on the specific alloy composition and processing technology.

CuNi1: This is a copper-nickel alloy with a low nickel content, usually around 1%. It maintains the excellent electrical and thermal conductivity of copper, while the addition of nickel improves its corrosion resistance.

CuNi2: A copper-nickel alloy containing about 2% nickel. Compared with CuNi1, its corrosion resistance is improved and is often used to manufacture corrosion-resistant electrical equipment and components.

CuNi10: A copper-nickel alloy with a nickel content of about 10%. Due to its higher nickel content, it has better seawater corrosion resistance and is suitable for equipment manufacturing in marine environments.

CuNi44: This is a copper-nickel alloy with a nickel content of 44%, also known as white copper. It has excellent corrosion resistance, especially to ammonia and hydrogen sulfide, and is commonly used in the chemical industry.

6J8: This is a special grade of copper-nickel alloy, usually used to manufacture precision resistors and thermocouples, with stable resistivity and good thermoelectric properties.

6J11: This alloy has a high nickel content, usually around 30%. It has good mechanical properties and corrosion resistance, and is suitable for manufacturing high-strength, high-corrosion-resistant components.

6J13: This is a copper-nickel alloy with a higher nickel content. It has excellent heat resistance and corrosion resistance and is often used to manufacture parts that work at high temperatures, such as aerospace engine parts.
