Abstract
PURPOSE: To provide a permanent magnet that has large residual magnetic flux density and retentivity and that can be ground, by forming a mold of magnetic powder composed of rate-earth elements, cobalt, copper, iron, hafnium in specified quantities, added with plastic resin as adhesive.
CONSTITUTION: A magnetic powder of the composition expressed by the general formula R[Co1-u-v-wCuuFev(Hf+M)w]z is added with plastic resin, 0.8W14wt%, as adhesive, and thereby a permanent magnet is formed. Here, 0<u≤0.20, 0.01< v≤0.60, 0.005<w≤0.05, 6.5≤z≤8.8. By adding Hf in this way, even if the addition of Cu is small, high retentivity Hc can be obtained, and even if Fe is increased, Hc does not fall. As adhesive, plastic resin, such as liquid epoxy resin, or polyacetal resin is used. By this, grinding and processing are made much easier.
