resistance wire Constantan
Features:(compared with the manganins)
It is a kind of resistance alloy 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 manganins.
Applications:
Usages 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.
Advantages:a,very good resistance to corrosion
b,very good malleability
c,very good solderabilit
