Abstract: 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.

Abstract: An aluminum alloy composition includes, in weight percent: 0.7-1.10 manganese; 0.05-0.25 iron; 0.21-0.30 silicon; 0.005-0.020 nickel; 0.10-0.20 titanium; 0.014 max copper; and 0.05 max zinc, with the balance being aluminum and unavoidable impurities. The alloy may tolerate higher nickel contents than existing alloys, while providing increased corrosion resistance, as well as similar extrudability, strength, and performance. Billets of the alloy may be homogenized at 590-640° C. and controlled cooled at less than 250° C. per hour. The homogenized billet may be extruded into a product, such as an aluminum alloy heat exchanger tube.
