Copper nickel alloy has low electric resistance,good heat-resistant and corrosion-resistant,easy to be processed and lead welded.
It isused 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.
