摘要： A sintered ferrous alloy which is high in wear resistance and relatively weak in the tendency to abrade another metal material with which the sintered alloy makes rubbing contact and suitable for rocker arm tips in automotive engines for example. The sintered alloy is produced by compacting and sintering a powder mixture of 15-50 parts by weight of a Fe-Cr-B alloy powder, which contains 10-35% of Cr and 1.0-2.5% of B, 1.0-3.5 parts by weight of graphite powder, such an amount of a Cu-P alloy powder that the powder mixture contains 0.2-1.5% of P and 1.0-20.0% of Cu and the balance of an iron powder.

摘要： 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.

摘要： A sintered ferrous alloy which is high in wear resistance and relatively weak in the tendency to abrade another metal material with which the sintered alloy makes rubbing contact. The sintered alloy is produced by compacting and sintering 100 parts by weight of a powder mixture of 5-35 parts by weight of a Fe-Cr-B-Si alloy powder, which contains 10-35% of Cr, 1.0-2.5% of B and 0.5-3.0% of Si, such an amount of a Cu-P alloy powder that the powder mixture contains 0.2-1.5% of P and 1.0 to 20.0% of Cu, and the balance of a cast iron powder. Preferably the cast iron powder contains 2.5-3.5% of C, 1.8-2.2% of Si and 0.6-1.0% of Mn. For example, the sintered alloy is suitable for rocker arm tips in automotive engines.
