Abstract
PURPOSE:To obtain the permanent magnet having both superior magnetic characteristic and cutting workability of a method wherein an alloy powder in specific composition of rare earth and cobalt is formed, and the material sintered at a given temperature is impregnated with a thermosetting resin. CONSTITUTION:The alloy powder whose composition is shown in formula I, whose R represents one kind of more of rare earth element including Y, and M represents Cu and Fe; an alloy powder given in 0<=x<=0.5, 6<=z<=8.5, is subjected to press forming in a magnetic field, for example, at 10,000Oe, the material thus obtained is sintered at temperatures 700-1,150 deg.C, however, the temperature coming below 700 deg.C will induce an inferior magnetic characteristic in this case, but that of exceeding 1,150 deg.C may give an unsatisfactory workability for cutting despite improving magnetic characteristic. The sintered material is soaked in a tank of thermosetting resin like epoxy resin for impregnation. The magnetic characteristic can thus be improved along with workability.
