| Step | Description |
|---|---|
| Mixing | Mix the ingredients |
| Melting | Dissolve the mixture at high temperature and prepare an alloy |
| Fine pulverization | Turn the alloy into fine powder |
| Molding in a magnetic field | When pressing the fine powder, apply a magnetic field to it and prepare a molded product |
| Sintering and heat treatment | Sinter the product at about 1,100℃, then subject it to heat treatment at about 600℃ |
| Processing | Process the manufactured magnet base material into the product shape |
| Surface treatment | Subject the product to surface treatment to make it rustproof |
| Magnetization | Apply a magnetic field to give the magnet magnetism |
