Soft magnetic alloys are easily magnetized and demagnetized. They are uniquely suited for specialized applications that require high permeability, low losses, and low residual magnetism. Only several alloy families meet these characteristics. These include certain nickel-irons, silicon-irons, cobalt-irons, ferritic stainless steels, and pure iron. Selection of a particular alloy requires careful consideration.

Typical applications include: EMI shielding, specialty transformer laminations, high quality motor laminations, and electrical generators. They are also selected for use as pole pieces for electromagnets, relays, solenoids, transducers, magnetic bearings, and components in scientific instruments.
