CuNi34 copper-nickel alloy wire

CuNi34 copper-nickel alloy wire
Product Details

Common Name: CuNi34, NC40.

Copper-nickel alloy (Cu56Ni34 alloy) with low resistivity for use at temperatures up to 350°C. It 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.
