Product Description

0.05mm Copper Nickel/Constant/Advance Shiny Soft Resistance Wire

Product Description

Resistance alloy with moderate resistivity and low temperature coefficent of resistance with a flat resistance/temperature curve over a wider range than the "manganins". CuNi44 Alloy wire also shows better corrosion resistance than the man ganins. Uses tend to be restricted to ac circuits. CuNi44/ CuNi40 /CuNi45 Constantan Copper Nickel Alloy Wire is also the negative element of the type J thermocouple with Iron being the positive; type J thermocouples are used in heat treating applications. Also, it is the negative element of the type T thermocouple with OFHC Copper the positive; type T thermocouples are used at cryogenic temperatures.
