<P>PROBLEM TO BE SOLVED: To utilize resource effectively by increasing the mixing ratio of reclaimed magnetic powder to the virgin magnetic powder. <P>SOLUTION: The unusable part of a magnet body produced by performing hot plastic processing of a material, containing virgin magnetic powder obtained by rapid quenching, is subjected to hydrogen absorption pulverization thus obtaining a reclaimed magnetic powder for magnet production. The reclaimed magnetic powder is mixed with the virgin magnetic powder at a ratio of 40-80 mass% of the total quantity to produce a mixed magnetic powder, which is then subjected to hot plastic processing thus obtaining a magnet body. <P>COPYRIGHT: (C)2013,JPO&INPIT |
