Zusammenfassung:	PCT No. PCT/SE95/00445 Sec. 371 Date Oct. 11, 1996 Sec. 102(e) Date Oct. 11, 1996 PCT Filed Apr. 24, 1995 PCT Pub. No. WO95/29490 PCT Pub. Date Nov. 2, 1995The invention concerns a method of compacting and heat-treating iron powders in order to obtain magnetic core components having improved soft magnetic properties. The iron powder consists of fine particles which are insulated by a thin layer having a low phosphorous content. According to the invention, the compacted iron powder is subjected to heat treatment at a temperature between 350 DEG and 550 DEG C.
