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

super permalloy


magnetic steel alloys

Ohmalloy-1J46 is a nickeliron magnetic alloy, with about 46% nickel and iron content. It is derived in accordance with permalloy. It has characteristics of high permeability and high saturation magnetic flux density.
Alloy melting in a vacuum medium, cast into ingots, after hot forging blanks made of sheet metal, and then after hot rolling, pickling, surface treatment, cold rolling into finished products.
Ohmalloy-1J46 Iron-nickel alloy( soft magnetic alloy) mostly in an alternating magnetic field used mainly for high magnetic yoke, sensitive relays, low-loss micro-motor, small power transformers, pulse transformer, transistor switches, magnetic amplifier magnetic modulator, sensitive signal input and output transformers, magnetic heading aviation instrumentation magnetic sensor, magnetic susceptibility measurement instrument components, precision meter movable piece and the stator magnetic shielding and magnetic temperature compensation element.
