3 . The can tab of claim 1 , wherein the 3XXX aluminum alloy comprises about 2% Mg or about 3% Mg.
4 . The can tab of claim 1 , wherein the 3XXX aluminum alloy is a AA3104 aluminum alloy or a AA3204 aluminum alloy.
5 . A can end comprising a 3XXX aluminum alloy.
6 . The can end of claim 5 , wherein the 3XXX aluminum alloy comprises about 0.15-0.40 wt % Si, about 0.30-0.55 wt % Fe, up to 0.10 wt % Cu, about 0.70-0.90 wt % Mn, about 0.50-3.10 wt % Mg, up to 0.05 wt % Cr, up to 0.15 wt % Zn, up to 0.05 wt % Ti, and up to 0.15 wt % impurities, with remainder Al.
7 . The can end of claim 5 , wherein the 3XXX aluminum alloy comprises about 2% Mg or about 3% Mg.
8 . The can end of claim 5 , wherein the 3XXX aluminum alloy is a AA3104 aluminum alloy or a AA3204 aluminum alloy.
9 . The can end of claim 5 , wherein the can end is a 2 inch diameter can end or a 2 inch ⅛″ diameter can end.
10 . An aluminum can comprising a tab comprising a 3XXX aluminum alloy, an end comprising a 3XXX aluminum alloy, or both the tab and the end comprise a 3XXX aluminum alloy.
11 . The aluminum can of claim 10 , wherein the can comprises the tab comprising a 3XXX aluminum alloy and the end comprising a 3XXX aluminum alloy.
12 . The aluminum can of claim 11 , wherein the can further comprises a body comprising a 3XXX aluminum alloy.
13 .
