Zusammenfassung:	PURPOSE:To manufacture a wear resistant sintered iron alloy for a sliding current collector such as a sliding plate for a pantograph by subjecting a powdery material consisting of granular or powdery chrome, metallic sulfide, phosphorus and iron powder in a specified weight ratio to mixing, compression molding and sintering to form a sintered alloy matrix and by impregnating the specified amount of lead or a lead alloy into the alloy matrix. CONSTITUTION:A powdery material is composed of 2-14wt.% granular or powdery chrome, 2-7wt.% metallic sulfide,
