Product Description
Enamelled CuNi1 is a copper-nickel alloy (Cu99Ni1 alloy) with low resistivity for use at temperatures up to 200° C.
Enamelled CuNi1 is kind of low resistance (heating) alloy. It is one of the key materials of the low-voltage electrical products. It is widely used in low-voltage circuit breaker, electric blankets.thermal overload relay and other low-voltage electrical product.
