Nickel Alloy Constantan Wire CuNi14 220 V Electrical Heating Resistance Wire
 
OhmAlloy020 (Resistance heating wire and resistance wire)
Common Name:CuNi14,CN20

OhmAlloy020 is a copper-nickel alloy (Cu86Ni14 alloy) with low resistivity for use at temperatures up to 300°C.

OhmAlloy020 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.

OhmAlloy020 is typically used for low-temperature applications such as floor heating cables.
