Product Description

2mm Chrome Nickel Wire Resistance Spiral Heating Resistance Wire Cu56Ni34 Strip/Wire
 
OhmAlloy040 (Resistance heating wire and resistance wire)
Common Name:Cu56Ni34,CN40

OhmAlloy040 is a copper-nickel alloy (Cu56Ni34 alloy) with low resistivity for use at temperatures up to 350°C.

OhmAlloy040 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.

OhmAlloy040 is typically used for low-temperature applications such as heating cables.
