OhmAlloy25(Resistance heating wire and resistance wire)
(Common Name:CuNi19,NC25)
OhmAlloy25 is a copper-nickel alloy (Cu81Ni19 alloy) with low resistivity for use at temperatures up to 300℃.
OhmAlloy25 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.
OhmAlloy25 is typically used for low-temperature applications such as heating cables.
