Nd_Fe_B magnet is Anisotropic sintered magnet which is composed basically of Neodymium, Iron and Boron. Its main phase is newly found Nd Fe B intermetallic compound with a tetragonal crystal structure. Surface coating is very important for anti-corrosion.

Due to high performance magnetic characteristics, it could be reduce product size and weight, and also could be superior in corrosion resistance by surface coating.

- Sintering and plastic forming after mixing Neodimum & iron & Boron
