China Cu-Ni alloy heating resistance wire CuNi1 resistance wire Manufacture and Factory

Cu-Ni alloy heating resistance wire CuNi1 resistance wire

Short Description:

Copper Nickel Alloy is mainly made of copper and nickel. The copper and nickel can be melted together no matter what percentage. Normally the resistivity of CuNi alloy will be higher if the Nickel content is larger than Copper content. From CuNi1 to CuNi44, the resistivity is from 0.03μΩm to 0.49μΩm. That will help the resistor manufacture choosing the most suitable alloy wire.

General Description
Due to has high tensile strength and increased resistivity values, copper nickel alloy wires are the first choice

for applications as resistance wires. With the different nickel amount in this product range, the characteristics

of the wire can be chosen according to your requirements. Copper nickel alloy wires are available as bare wire,
