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.

CuNi23 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.

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.
