China CuNi2 Cuprothal 5 Copper Nickel Alloy Wire Manufacture and Factory

CuNi2 Cuprothal 5 Copper Nickel Alloy 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.
