ABSTRACT:
An aluminum alloy for internal-combustion engine pistons has good high-temperature strength and good abrasion resistance. It comprises from 2 to 5% by weight of copper, from 13 to 16% by weight of silicon, from 0.2 to 1.3% by weight of magnesium, from 1.0 to 2.5% by weight of nickel from 0.05 to 0.2% by weight of vanadium and from 0.004 to 0.02% by weight of phosphorus, with the balance of aluminum. To produce the piston, a melt of the aluminum alloy having the defined composition is cast and then aged under heat at 220 to 260.degree. C. for 3 to 5 hours (T5 treatment) or, after having been cast, heated at 480 to 510.degree. C. for 3 to 10 hours for solution treatment and then aged under heat at 240 to 260.degree. C. for 3 to 5 hours (T6 or T7 treatment).
