Resistance Wire Constantan

resistance wire constantan 1,nickel 44% Copper 55% 2,dia:0.03-10mm 3,ISO9001:2000 certified; 4,lead time:7 days

 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
