Abstract

PURPOSE: To manufactue a permanent magnet material excellent in maximum energy integration and heat stability by the procedure in which a magnet alloy ingot composed mainly of a rare earth element and Co is subjected to solutionizing and aging treatments, ground, mixed with a binder, orientated in a magnetic field, and then molded by compression molding method.
CONSTITUTION: Raw materials compounded in a desired composition are melted in an inert gas such as Ar or under vacuum to obtain a magnet alloy ingot having a composition of 20W28wt% one or more of rare earth elements, 5W15wt% Cu, 0.2W5wt% Zr, 5W15wt% Fe, and 22W74.8wt% Co. Then, the ingot is kept at 1,000W1,250°C for 1W50hr., subjected to a aging treatment in various profile states, cooled, ground, mixed with a binder such as epoxy resin, orientated in a magnetic field, molded by compression molding method, and then solidified sufficiently.
