Introduction
Soft magnetic alloys are NiFe alloys that contain from about 35 to 81% of nickel. These alloys are
using in applications requiring the following characteristics: high permeability, high saturation
magnetostriction, low hysteresis energy loss,low eddycurrent loss in alternating flux, low curie
temperature, vonstant permeability with changing temperature.
tape recorder head laminations and so on.
