PROBLEM TO BE SOLVED: To produce an aluminum alloy excellent in heat resistance and wear resistance, and its production. SOLUTION: This aluminum alloy has a composition consisting of, by mass, 10-30% Si, 1-5% Ti, 3-10%, in total, of at least either of Fe and Ni, 0.05-1.0% Mg, and the balance essentially Al. Further, the average crystalline grain size of Si is <=2μm, and the average grain size of intermetallic compound phases other than Si is <=1μm.
