The present disclosure provides Al—Si—Mg aluminum alloys comprising a deliberate addition of Mn between 0.05-0.40 weight percent to increase at least one tensile property (such as the yield strength) of an aluminum product comprising such alloy. The Al—Si—Mg alloy comprises, in weight percent, 5-9% Si, 0.35-0.75% Mg, 0.05-0.4% Mn, less than 0.15% Fe, up to 0.15% Ti, 0.005-0.03% Sr and the balance being aluminum and unavoidable impurities, wherein the unavoidable impurities may be present in an amount of up to 0.05% each and up to 0.15% total. The present disclosure provides a foundry ingot comprising the above Al—Si—Mg aluminum alloy, a process for making the above Al—Si—Mg aluminum alloy and an aluminum alloy obtainable by said process.
