Professional Design Terminal Pins - Cu-Ni Low resistance CuNi23 (alloy 180) Copper Nickel Alloy Wire / Flat Wire – TANKII Detail:
The copper-based low resistance heating alloy is widely used in low-voltage circuit breaker, thermal overload relay, and other
low-voltage electrical product. It is one of the key materials of the low-voltage electrical products. The materials produced
by our company have the characteristics of good resistance consistency and superior stability. We can supply all kinds of
round wire, flat and sheet materials.

sheet materials.
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.
