1J50 Foil Transformer Iron Core High Magnetic Permeability 0.05mm Thick
OhmAlloy-1J50 (Soft magnetic alloy)
(Common Name: Ni50, E11a, 50H, Hy-Ra49, PB)
Ohmalloy-1J50 is a nickel–iron magnetic alloy, with about 50% nickel and 48% 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-1J85 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.
