Soft magnetic alloy
Soft magnetic alloy having a high magnetic permeability and low coercive force in a weak magnetic field for a class of alloys. Such alloys are widely used in radio-electronic industry, precision instruments, remote control and automatic control system, mainly used for energy conversion and information processing in two areas.
