Soft Magnetic Alloys

Basic Properties: Soft magnetic alloys are magnetic alloys that are easily magnetized under an external magnetic field and lose their magnetic induction intensity once the external field is removed. The term "soft" refers to the ease with which these materials can be magnetized, exhibiting "soft" magnetic properties. Soft magnetic alloys include low-carbon electrical steel, Armco iron, silicon steel sheets, nickel-iron soft magnetic alloys, iron-cobalt soft magnetic alloys, and iron-silicon-aluminum soft magnetic alloys, etc.
