Cu-Ni Low resistance CuNi23 (alloy 180) Copper Nickel Alloy Wire / Flat 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.

    The copper-based low resistance heating alloy is widely used in low-voltage circuit breaker, thermal overload relay, and other

    low-voltage electrical product. It is one of the key materials of the low-voltage electrical products. The materials produced

    by our company have the characteristics of good resistance consistency and superior stability. We can supply all kinds of

    round wire, flat and sheet materials.

    sheet materials.

    The alloy is non-magnetic. It is used for electrical regenerator’s variable resistor and the strain resistor,
    potentiometers, heating wires, heating cables and mats. Ribbons are used for heating of bimetals. Another field of application

    is manufacturing of thermocouples because it develops a high electromotive force (EMF) in association with others metals.
