PURPOSE:To get a bond magnet having high magnetic property and oxidation resistance and being excellent in surface smoothness and dimension stability by combining thermoplastic resin with thermosetting resin as resin ingredients. CONSTITUTION:A magnetic material resin composite material is composed of 79.9-99.9wt.% rare earth-iron-nitrogen based magnetic powder, 0.1-20wt.% thermosetting resin, and 0.1-20wt.% thermoplastic resin. Using this magnetic material resin composite material, a a bond magnet is manufactured by compression-molding, extrusion-molding, or injection molding, or the like. Hereby, a magnetic material resin composite material can be gotten, which contains rare earth-iron-nitrogen material small in grain diameter and having high magnetic property and besides has high magnetic field orientation property, corrosion resistance, and oxidation resistance. Furthermore, using these material, a high magnetic property of bond magnet excellent in surface smoothness and dimension stability can be manufactured. |
