Sintered Ferrite includes BaO.6Fe2O3 and SrO.6Fe2O3. It has comparatively simple production technology, low raw material price without rare earth elements, such as cobalt, nickel, etc. In addition, it has modest performance, strong coercive force and power demagnetizing energy resistance. It is a permanent-magnet material with the widest modern application used in permanent-magnet machine, loudspeaker, etc. 

Sintered Ferrite can work under the temperature of -40 to +200 °C. It is hard and crisp, so it can be cut and processed by emery tools.

As its main raw material is oxide, so it is not influenced by environment or chemicals (except several strong acids).
