0.25mm CuNi23 Copper Nickel Alloy Wire Bright For Resistor
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.

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.
