ABSTRACT OF THE DISCLOSURE Moderate strength extrudable dilute Al-Mg-Si aluminum base alloys are prepared comprising from 0.30 to 0.60% magnesium, from 0.45 to 0.70% silicon and from 0.10 to 0.30% copper, which may also include controlled amounts of elements such as chromium, zirconium, manganese, iron, zinc and titanium, wherein the silicon content must not exceed more than 0.30% over that needed to combine with magnesium and iron. Such alloys display lower hot flow stresses and reduced quench sensitivity as compared to AA Alloy 6063 while achieving the same strength levels.
