Product Description

Precison MWS Copper nickel alloy Resistance Cuprothal 294 Wire

Constantan Eureca  Wire / Flat Wire
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.
