Product Description

Constantan/CuNi40/6J40 Copper Wire Electric Heating Wire

Product Indroduction:
Constantan is CuNi40,also named 6J40,it is a resistance alloy which is mainly made up of copper and nickel.

It has the low resistance temperature coefficient,wide working temperature scope(500 below),good machiningproperty,anti-corrosive and easy braze welding.

The alloy is non-magnetic. It is used for electricalregenerator's variable resistor and the strain resistor,
potentiometers, heating wires, heating cables and mats. Ribbons are used for heating of bimetals. Another field of application is manufacturing of thermocouples because it develops a high electromotive force (EMF) in association with others metals.
