Copper nickel low resistant manganin resistance alloy wire CuNi19
CuNi resistance 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. It is also an important material for electrical heating cable.
