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. Chemical Content, %NiMnFeSiCuOtherROHS DirectiveCdPbHgCr441.50%0.5-Bal-NDNDNDND Mechanical PropertiesMax Continuous Service Temp400
