摘要： To provide a wear resistance comparable with that of the conventional A390 series aluminum alloys, a reduced attacking to a sliding counterpart, and an improved machinability, a wear-resistant cast aluminum alloy comprises: a chemical composition consisting, in weight percentage of: 14.0-16.0 Si, 2.0-5.0 Cu, 0.1-1.0 Mg, 0.3-0.8 Mn, 0.1-0.3 Cr, 0.01-0.20 Ti, 0.003-0.02 P, 1. 5 or less Fe, and the balance of Al and unavoidable impurities in which the Ca content is limited to not more than 0.005; and a microstructure in which a primary Si crystal and Al-Si-Fe-MnCr-based intermetallic compounds are dispersed in the form of a crystallized particle having a diameter of from 5 to 30 gm. A process of producing a wear-resistant cast aluminum alloy includes casting a melt of the alloy composition at a cooling rate of from 50.degree. to 200.degree. C./sec.
