32 . The method of claim 31 , wherein at least about 95% of the melt composition is derived from scrap, wherein the scrap comprises used beverage containers, wherein the melt composition comprises at least about 0.50 wt. % but no more than about 0.80 wt. % manganese, at least about 1.4 wt. % but no more than about 1.9 wt. % magnesium, at least about at least about 0.15 wt. % but no more than about 0.3 wt. % copper, and at least about 0.2 wt. % but no more than about 0.5 wt. % iron, wherein the final melt composition comprises no more than about 5 wt. % prime aluminum, wherein the sum total of all incidental materials and impurities does not exceed about 0.05 wt. % of the melt composition, and wherein the article comprises at least about 0.85 wt. % but no more than about 9 wt. % manganese, at least about 1.53 wt. % but no more than about 1.7 wt. % magnesium, and no more than about 0.35 wt. % copper.
