I search for Nichrome plate long time, and successfully bought it from Ohmalloy material. OHMALLOY provide real good service in alloy service and can always help me in finding the correct resistance alloy.

—— Mike Harness

OHMALLOY can provie me only 1kg Kovar alloy wire 1.0mm with short time, that is really amazing. Thanks

—— Janey

Really professional in thermocouple wire and cable, what i want just can get from OHMALLOY

—— Chris

Enamelled Constantan 0.08mm, i never expect to get only 2kg of it. But OHMALLOY supply it to me with good quality. God Jesus! Such a reliable supplier from china

OhmAlloy012 (Resistance heating wire and resistance wire)

Common Name:CuNi8,Alloy12,CN12

 

OhmAlloy012 is a copper-nickel alloy (Cu82Ni12 alloy) with low resistivity for use at temperatures up to 250°C.

 

OhmAlloy012 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.

 

OhmAlloy12 is typically used for low-temperature applications such as floor heating cables.
