A method of making a bonded permanent magnet including the steps of dissolving, in a solvent, an uncured epoxy resin having an incorporated catalyst which is inactive at a temperature of about 120 DEG F. Particles of a rapidly quenched rare earth-iron-boron alloy are added to the epoxy resin solution. The solution with the particles are mixed at a temperature of about 120 DEG F. until the solvent is removed and the magnetic particles are substantially uniformly coated with the resin. The epoxy coated particles are then cold-pressed into a compact to form a magnet and the epoxy compact is then cured by heating. |
