PCT No. PCT/JP93/00611 Sec. 371 Date Feb. 13, 1995 Sec. 102(e) Date Feb. 13, 1995 PCT Filed May 11, 1993 PCT Pub. No. WO93/23858 PCT Pub. Date Nov. 25, 1993The addition of a chelating agent or a chelating agent and an antioxidant in combination to a rare-earth bonded magnet composition and a rare-earth bonded magnet comprising a rare-earth magnetic powder and a resin component can provide improved moldability and magnets having high performance and high corrosion resistance. Further, the regulation of property values of the magnet composition enables the occurrence of troubles to be avoided during molding, resulting in improved productivity. Furthermore, the use of at least two resins as a resin component in an extruding composition contributes to improvement in moldability and consequently increase in throughput. Furthermore, the use of extrusion, involving setting by cooling, and not compression molding in the production of magnets can provide high-density, high-performance magnets.
