OhmAlloy30(Resistance heating wire and resistance wire)
(Common Name:CuNi23,NC30,Curpothal30)
OhmAlloy30 is a copper-nickel alloy (Cu77Ni23 alloy) with low resistivity for use at temperatures up to 300°C.
OhmAlloy30 is typically used for applications such as heating cables, fuses, shunts, resistors and various types of controllers.
