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

transformer iron core


power transformer core material

Frequency Transformer Iron Core 50-60 Hz Long - Term Work Low Loss


Application area:Frequency transformer iron core(50-60Hz)

IF power transformer iron core (400Hz-15kHz)

Switch power transformer iron core ( below 10kHz)


Filter reactor, filtering and energy storage inductor,


Power factor correction inductor core( below 50kHz)

Saturable reactor,Pulse compressor iron core

High Saturation magnetic induction - reduce transformer volume

High magnetic permeability low coercive force- improve transformerefficiency

Low loss(Equivalent 1/3 1/5 of silicon steel sheet)- reduce transformer temperature rise


 Good temperature stability - under 130℃ for long-term work
