PURPOSE:To obtain a compsn. for a permanent magnet, etc. having an excellent magnetic characteristic, mechanical characteristic and workability by pulverizing a sintered rare earth-Fe-Co-B magnet, adding a suitable ratio of resin thereto and subjecting the mixture to kneading and molding in a magnetic field. CONSTITUTION:The sintered magnet consisting essentially of rare earth element such as Y or Nd, Fe, Co and B is pulverized. The epoxy or other resin is added at 1-20wt% to such powder and the mixture is kneaded and is molded in the magnetic field. The preferable compsn. of the sintered magnet is R(Fe1-x-yCoxBy)z with 0<=x<=0.6, 0.02<=y<=0.2, 4.0<=z<=8.0. The ferromagnetic magnet having the excellent magnetic performance and intricate shape is inexpensively produced if such compsn. is used. |
