Product Description

Copper-based low resistance heating alloy wire

Copper-based heating resistance alloy wire has lower electrical resistance, good mechanical, 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. It is also an important material for electrical heating cable.

 

Copper nickel alloy series: CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23,CuNi30, CuNi34, CuNi44. Also named NC003, NC005, NC010, NC012, NC015, NC020, NC025, NC030, NC035, NC040, NC050
