    CuNi40 Copper nickel alloy Precision Alloy Constantan resistance wire Apply to strain resistance

    CuNi40 6j40 Copper nickel alloys Constantan resistance strip

    Product Description
    Product Description
    Constantan Wire with moderate resistivity and low temperature coefficent of resistance with a flat resistance/temperature curve over a wider range than the "manganins". Constantan also shows better corrosion resistance than the man ganins. Uses tend to be restricted to ac circuits.

    Constantan 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.
