General Description
Due to has high tensile strength and increased resistivity values,
copper nickel alloy wires are the first choice for applications as
resistance wires. With the different nickel amount in this product
range, the characteristics of the wire can be chosen according to
your requirements. Copper nickel alloy wires are available as bare
wire, or enamelled wire with any insulation and self-bonding
enamel. Furthermore, litz wire made of enamelled copper nickel
alloy wire are available.

Application of CuNi2
CuNi2 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.
