Low Resistance Copper Based Alloys CuNi30 Wire 38 0.152mm For Heating Cable

 

OhmAlloy35(Resistance heating wire and resistance wire)
(Common Name:CuNi30,NC35.Cu70Ni30)

 

OhmAlloy35 is a copper-nickel alloy (Cu70Ni30 alloy) with low resistivity for use at temperatures up to 350°C.

 

OhmAlloy35 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.

 

OhmAlloy35 is typically used for low-temperature applications such as heating cables.
