Provided herein are novel aluminum alloy compositions and methods of making and processing the same. The alloys described herein can be used in bottle making applications and exhibit enhanced runnability, formability, and appearance. The methods of producing an aluminum alloy sheet described herein can include casting an aluminum alloy to form an ingot, homogenizing the ingot, hot rolling the ingot to produce a hot band, and cold rolling the hot band to an aluminum alloy sheet of final gauge.
An aluminum alloy comprising 0.2-0.8 wt. % Fe, 0.05-0.50 wt. % Si, 0.40-1.65 wt. % Mg, 0.40-1.50 wt. % Mn, 0.03-0.35 wt. % Cu, up to 0.07 wt. % Cr, up to 0.05 wt. % Ni, up to 0.07 wt. % Ti, up to 0.35 wt. % of Zn, up to 0.04 wt. % Zr, up to 0.15 wt. % impurities, with the remainder as Al, and wherein the alloy comprises an Effective Mg Index up to about 0.9.
