OhmAlloy012 (Resistance heating wire and resistance wire)

Common Name:CuNi8,Alloy12,CN12

OhmAlloy012 is a copper-nickel alloy (Cu82Ni12 alloy) with low resistivity for use at temperatures up to 250°C.

OhmAlloy012 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.

OhmAlloy12 is typically used for low-temperature applications such as floor heating cables.
