CuNi8 copper-nickel alloy wire

CuNi8 copper-nickel alloy wire
Product Details

Common Name: CuNi8, Alloy12, CN12

CuNi8 is a copper-nickel alloy (Cu82Ni12 alloy) with low resistivity for use at temperatures up to 250°C.

CuNi8 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.

CuNi8 is typically used for low-temperature applications such as floor heating cables.
