Rare Earth Magnet Basics / Glossary of Magnet Terms / Sintered magnet
- Sintered magnet
- A magnet produced with what is called a powder metallurgical process. Currently, a sintered magnet often means a rare earth sintered magnet. After the magnet alloy is finely pulverized, the easy magnetization axis is aligned in the magnetic field, the material is press molded, then it is sintered. Since the sintering contraction is large, the dimensional precision is poor and generally, processing is required after sintering. Compared to bond magnets produced by mixing in plastic, since there is no plastic or other non-magnetic section, the magnetic characteristics are high and the heat resistance is superior.
