PCT No. PCT/SE95/00497 Sec. 371 Date Nov. 5, 1996 Sec. 102(e) Date Nov. 5, 1996 PCT Filed May 5, 1995 PCT Pub. No. WO95/30502 PCT Pub. Date Nov. 16, 1995The present invention concerns low allow PM materials which after single pressing and sintering utilizing traditional powder metallurgy processes and equipment combine high mechanical strength and high density with maintained precision of tolerance. As base material is used an iron powder having at least one alloying element diffusion-bonded to the outer surfaces of unalloyed iron particle is provided.
