CuNi 30 / CuNi 44 Resistance Wire /Nickel Alloy 30/Cuprothal 30
Resistance Wire
Product Description
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.
CuNi30 low resistance heating alloy is widely used in low-voltage

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.
