Cuni1 is a kind of copper nickel alloy, which have low resistivity for use at temperature upt to 200 ℃. CuNi1 Copper nickel alloy also has 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.
