Title:
ALLOY FOR USE IN BONDED MAGNET, ISOTROPIC MAGNET POWDER AND ANISOTROPIC MAGNET POWDER AND METHOD FOR PRODUCTION THEREOF, AND BONDED MAGNET
Document Type and Number:
WIPO Patent Application WO/2003/085147
Kind Code:
A1
Abstract:
An alloy for use in a bonded magnet, characterized in that it comprises iron (Fe) as a primary component, 12 to 16 atomic % of a rare earth element (R) including yttrium (Y), and 10.8 to 15 atomic % of boron (B). A magnet powder produced through subjecting the above magnet alloy to the d−HDDR treatment or the like is capable of providing pellets which are significantly easier to feed into a mold for forming a bonded magnet, which leads to the reduction of a bonded magnet excellent in magnetic characteristics at a reduced cost.
