CuNi44 Constantan Konstantan Wire resistance heating wire for Electric Blanket
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.
