Copper nickel CuNi34 alloy has low electric resisitance, which have 34% nickel and balance is copper, it is 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.
CuNi34 Copper Nickel alloy resistance heating strip.
