Product Description

Copper Nickel Alloy Wire:

Model: CuNi1~CuNi44

Copper Nickel alloy wire has lower electrical resistance, good echanical, excellent welding and anti-corrosion properties. It is used to make the key components in the thermal overload relay, low resistance thermal circuit breaker, and the electrical appliances. 
Besides, it is also an important material for electrical heating wires, heating cables. For example, many underfloor heating cables conductors are copper nickel alloy wires.
