| ND-FE-B MAGNET (SINTERED) |
| (I) Introduction: |
| Nd-fe-b magnet which is an anisotropic sintered magnet composed basically of neodymium, iron and boron. Its main phase is a newly-found Nd Fe B intermetallic compound with a tetragonal crystal structure. An outstanding energy product 45 MGOe have been obtained in mass production. Surface coating is very important for anti-corrosion. |

| Surface coating: |
| 1. Nickel plating 2. Zinc plating 3. Tin plating 4. Epoxy resin coating |
