General Description
CuNi alloy is a copper-nickel alloy (CuNi alloy) with medium resistivity for medium-low temperature resistances. The alloy is suitable for use at temperatures up to 400° C (750° F)

CuNi alloy wire is very malleable and has a good resistance to corrosion until temperatures of 400° C. Ideal applications areas are all types of resistances used at low temperature.

CuNi alloy wireis typically used in heating cables, fuses, resistors and various types of controllers.
As a big manufacturer and exporter in China on the line of electric resistance alloy, we can supply all kinds of electric resistance alloy wire and strips (resistance steel wire and strips weiding wire),
