PURPOSE:To obtain a highly oriented magnet by a method wherein rare-earth alloy powder is kneaded with resin and then subjected to preliminary magnetization or alloy powder is subjected to preliminary magnetization and then kneaded with resin and the kneaded material is molded. CONSTITUTION:Rare-earth alloy is melted and subjected to a thermal treatment such as solutionization or aging. Then, after the alloy is subjected to a rough grinding process, and a fine grinding process, the alloy powder is kneaded with resin and subjected to preliminary magnetization or the alloy powder is subjected to preliminary magnetization and kneaded with resin. Further, the kneaded material is molded and the molded product is magnetized. Rare- earth-transition metal system alloy is employed as the rare-earth alloy. With this constitution, a highly oriented resin-bound rare-earth magnet can be manufactured under an industrially available molding magnetic field. |
