PURPOSE:To develop a magnet excellent in toughness as well as in magnetic properties, by mixing the powders of specific low-m.p. metals with the powder of an R2Co17 magnet such as Sm2Co17, etc., and by subjecting the resulting powder mixture to hot compaction. CONSTITUTION:The ingot to a magnet represented by R2Co17 (where R is at least one kind among Y and rare earth metals) such as Sm2Co17, etc., is crushed, to which powders of low-m.p. metals such as Al, Pb, Sn, Zn, etc., are added by 5-35% by volume ratio to undergo mixing. The resulting powder mixture is hot-compacted at >=400 deg.C, so that R2Co17 magnet free from cracks, breakage, slip, etc., and excellent in magnetic properties can be obtained. |
