PROBLEM TO BE SOLVED: To provide an aluminum alloy with good thermal stability for the production of thermally and mechanically stressed cast components. SOLUTION: The aluminum alloy contains 11.0-12.0 wt.% silicon, 0.7-2.0 wt.% magnesium, 0.1-1 wt.% manganese, at most 1 wt.% iron, at most 2 wt.% copper, at most 2 wt.% nickel, at most 1 wt.% chromium, at most 1 wt.% cobalt, at most 2 wt.% zinc, at most 0.25 wt.% titanium, 40 ppm boron, optionally 80-300 ppm strontium, and aluminum as the reminder with further elements and impurities due to production individually at most 0.05 wt.%, in total at most 0.2 wt.%.
