Cupronickel Copper-Nickel Alloys CuNi1 Constantan Heating Resistance Wire in Wire/Flat Wire/Ribbon/Foil/Bar
 
OhmAlloy 3 (Resistance heating and resistance wire)

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.
