Copper Nickel Alloy NC020 CuNi14 Wire Strip Rod Uniform Resistance For Seaship Accessories
Common Name:CuNi14,NC20
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.
OhmAlloy20 is typically used for low-temperature applications such as heating cables.
