Everyone is familiar with ferrite, which can be divided into isotropy and anisotropy. According to different molding processes, anisotropic ferrite can be divided into dry pressing and wet pressing. According to the main components, ferrite permanent magnets are mainly divided into two types: barium ferrite (BaO · 6Fe2O3) and strontium ferrite (SrO · 6Fe2O3). Below, we will introduce the directionality, characteristics, and magnetic properties of barium ferrite and strontium ferrite.

In recent years, due to environmental and health reasons, barium based ferrites have been discontinued, and currently strontium based ferrites are mainly used in the market.

The main uses of barium ferrite and strontium ferrite;

The main products of permanent magnet ferrite are anisotropic series, which are particularly suitable for use as permanent magnets for small generators and motors. They can replace aluminum nickel cobalt permanent magnets and are used for making permanent magnet ignition motors, permanent magnet motors, permanent magnet ore separators, permanent magnet suspension heads, magnetic thrust bearings, magnetic separators, speakers, microwave devices, magnetic therapy films, hearing aids, etc.
