Method of manufacturing a permanent magnet. |
摘要 |
The invention describes a method of manufacturing a magnet on the basis of RE2Fe14B. To this end, a shaped body of the said composition is sintered by means of induction heating to a density exceeding 95% of the theoretical maximum density. The method according to the invention enables the manufacture of magnets having excellent properties in a very short time, these properties being: a high energy product, a large remanence, a high density, a large intrinsic coercive force and a small particle size.
