NC003 CuNi1 Alloy3 Wire Copper Nickel Alloy for Heating Cable on Floor or Roof
Common Name: CuNi1, Alloy3,HAI3.NC3
OhmAlloy 3 is a copper-nickel alloy (Cu99Ni1 alloy) with low resistivity for use at temperatures up to 200°C.
OhmAlloy 3 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.
