Product Description

Konstantan Foil / Konstantan Foil / Cuni44Mn1
Product Description
      Constantan Strip 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 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.
