Product Description

Copper Nickel Alloy Foil Constantan Strip/CuNi40 Tape/CuNi44 Alloy

Constantan  Definition

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.
