Electric resistance alloy

Copper-nickel (CuNi) alloys

CuNi alloy is a name of copper-nickel alloy with medium resistivity for medium-low temperature resistances. The alloy is suitable for use at temperatures up to 400°C. Resistance wire resists the flow of electricity. And it comes in various forms which include resistance tape, resistance ribbon or resistance strand. Ideal applications areas are all types of resistances used at low temperature.

Application:

electrical resistors, potentiometers, heating wires, heating cables and underground heating mesh; Braiding and shielding in flexible coaxial cable and communication cable, a variety of audio and video cable ,vehicle signal cable, network cable ,data transmission cables and so on.
