Abstract
A highly wear-resistant sintered ferrous alloy which consists essentially of 2.0-8.0% of Cr, 0.1-1.0% of B, 1.0-2.5% of Si, 0.3-1.2% of Mn, 1.2-3.8% of C, by weight, and the balance of Fe. The alloy is produced by compacting and sintering a powder mixture, which is preferably prepared by mixing 75-90 parts by weight of a cast iron powder with 25-10 parts by weight of a Fe--Cr--B--Si alloy powder.
