An overview of soft ferrite materials


Soft magnetic materials have very low coercivity and can be repeatedly magnetized in a magnetic field. When the external electric field is removed, all or most of the magnetic properties obtained will disappear.
Soft ferrite is produced by powder metallurgy method, and there are several types such as Mn-Zn, Cu-Zn, Ni-Zn, etc. Among them, Mn-Zn ferrite has the largest output and dosage.
Soft ferrite is divided into the following nine types: pure iron and low carbon steel, iron-silicon alloy, iron-aluminum alloy, iron-silicon-aluminum alloy, nickel-iron alloy, iron-cobalt alloy, soft ferrite, amorphous State soft magnetic alloy, ultra-microcrystalline soft magnetic alloy.
