is a nickel-iron soft magnetic alloy. The main component is composed of about 50% Ni, 48% fe and other trace elements. It has the characteristics of high magnetic permeability and high saturation magnetic induction.
Ni50 alloy is smelted in a vacuum induction furnace. After being cast into a steel ingot, it is hot forged into a slab, then after hot rolling, pickling, and surface finishing, it is cold rolled into a finished strip or forged into the required bar. It has a higher saturation magnetic induction intensity and lower coercivity, and has a lower static magnetic permeability in the iron-nickel soft magnetic alloy.
The process performance of Ni50 soft magnetic alloy is relatively stable, which creates good conditions for mass production of parts with relatively consistent magnetic properties. Most of these alloys are said to be used under alternating magnetic fields. They are mainly used for high-conductivity yoke irons, sensitive relays, low-loss micromotors, low-power power transformers, pulse transformers, transistor switches, magnetic amplifiers, magnetic modulators, and sensitive signals. Input and output transformers, magnetic sensors of aviation magnetic heading instruments, magnetic sensitive components in magnetic measuring instruments, moving and stators in precision electric meters, magnetic shielding and magnetic temperature compensation components.
