Abstract
The present invention provides a high-strength, abrasion resistant aluminum alloy having a composition represented by the general formula Al.sub.a M.sub.b X.sub.c Z.sub.d Si.sub.e, wherein M is at least one element selected from the group consisting of Fe, Co, and Ni; X is at least one element selected from the group consisting of Y, La, Ce and Mm (mischmetal); Z is at least one element selected from the group consisting of Mn, Cr, V, Ti, Mo, Zr, W, Ta and Hf; and a, b, c, d and e are all expressed by atom percent and range from 50 to 89 %, 0.5 to 10 %, 0.5 to 10 %, 0 to 10 % and 10 to 49 %, respectively, with the proviso that a+b+c+d+e =100 %, the alloy containing fine Si precipitates and fine particles of intermetallic compounds dispersed in an aluminum matrix. The aluminum alloy may further contain not greater than 5 % of at least one element selected from the group consisting of Cu, Mg, Zn and Li. The alloy can be warm-worked at 300.degree.-500.degree. C. and is useful for various industrial applications where high abrasion resistance and high strength are required.
