Constantan Wire Copper Nickel Resistance Wire CuNi1 CuNi2 CuNi6 CuNi8 CuNi10 Wire
Constantan Wire Copper Nickel Resistance Wire CuNi1 CuNi2 CuNi6 CuNi8 CuNi10 Wire
Description:
Copper nickel alloy, which has low electric resistance, good heat-resistant and corrosion-resistant, easy to be processed and lead welded. 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.
