LORK is a alloy manufacturer with 20 years of manufacturing experience.
Copper Nickel Alloy is mainly made of copper and nickel. The copper and nickel can be melted together no matter what percentage. Normally the resistivity of CuNi alloy will be higher if the Nickel content is larger than Copper content. From CuNi1 to CuNi44, the resistivity is from 0.03μΩm to 0.49μΩm. That will help the resistor manufacture choosing the most suitable alloy wire.
Constantan is CuNi40,also named 6J22,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 electrical regenerator'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.
Copper nickel alloy series:Constantan CuNi40 (6J40), CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23,CuNi30, CuNi34, CuNi44.
