Thermal Overload Relay Wire CuNi8 Alloy12 CN012 Low-voltage Low Temperature Heating
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.
