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

High Light:

toroidal transformer core material


transformer iron core

Application area:

Switch power transformer and Pulse transformer iron core

Power transformer , precision current mutual inductor iron core

Leakage protection switch mutual inductor iron core

Filtering inductance, storage inductance, the electric reactor iron core

EMC common mode inductance and differential mode inductance iron core

Saturable reactor, magnetic amplifier, Spike killer, Pulse Compressor iron core and magnetic bead


High Saturation magnetic induction - reduce transformer volume

High magnetic permeability low coercive force- improve transformer efficiency, mutual inductor sensitivity, reduce coil distribution parameters

Low loss- reduce transformer temperature rise

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

Lower price - has the best cost performance of all the metal soft magnetic material
