Abstract
An abrasion-resistant aluminum alloy consists of 13.0 to 16.0 percent by weight of Si, 4.0 to 5.0 percent by weight of Cu, at least 0.8 and less than 1.4 percent by weight of Mg, not more than 0.8 percent by weight of Fe, not more than 0.1 percent by weight of either P or at least one of Na, Sb and Sr and a remainder of Al and unavoidable impurities. The alloy's microstructure contains coarse Si particles of 15 to 40 .mu.m mean particle diameter, fine Si particles of not more than 5 .mu.m mean particle diameter and other fine particles, with a homogeneous dispersion of all of these particles. This abrasion-resistant aluminum alloy has specific abrasion loss of not more than 10.times.10.sup.-7 mm.sup.2 /kg.
