Abstract of the Disclosure: A cast article of aluminum alloy is produced by pouring into a mold a molten Al-Si-Mg type casting alloy having an antimony (Sb) content in the range of about 0.03% - 1.0% by weight and, while the aolloy cast body is cooling following complete solidification but before its temperature has fallen below 450°C, placing the solidified cast body into a heating furance kept at temperatures in the range of from 500 to 550°C and retaining it at an intermediately high-temperature within that temperature range for not more than 30 minutes, subsequently quenching said cast body in cold water or hot water and thereafter subjecting the quenched cast body to a conventional artificial aging treatment. The resulting cast articles are, in terms of strength, toughtness and resistance to thermal shocks, comparable with or superior to cast articles obtained by conventional methods but can be manufactured in a reduced period of time with consequential savings in cost.
