Cu-ni Alloy Resistance Wire 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 wires 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)
