Add to Cart
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-1J50 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.
