An aluminum alloy and recycle method are provided in which the recycled used beverage containers form an alloy composition useful with relatively minor or no compositional adjustments for body, end and tab stock, apart from magnesium levels.
Claims19
A beverage container comprising a body and an end, wherein the body and end each comprise an aluminum alloy, the aluminum alloys of the body and end each comprise manganese and magnesium, wherein:
- (i) the aluminum alloy of the body comprises from about 1 to about 2 wt. % magnesium;
- (ii) the aluminum alloy of the end comprises from about 4 to about 5.5 wt. % magnesium;
- and
- (iii) an absolute value of a difference between the manganese contents of the aluminum alloys is less than 0.3 wt. %.
A beverage container comprising a body and an end, the end comprising a connector to a tab for opening the container, the body and end each comprising an aluminum alloy, the aluminum alloys of the body and end each comprising manganese and magnesium, wherein:
- (i) the aluminum alloy of the body comprises from about 1.2 to about 2.0 wt. % magnesium and from about 0.25 to about 0.9 wt. % manganese;
- (ii) the aluminum alloy of the end comprises from about 4 to about 5 wt. % magnesium and from about 0.25 to about 0.9 wt. % manganese;
- and
- (iii) an absolute value of a difference between the manganese contents of the aluminum alloys is less than 0.3 wt. %.
A beverage container comprising a body and an end, the end comprising a connector to a tab for opening the container, the body and end each comprising an aluminum alloy, the aluminum alloys of the body and end each comprising manganese and magnesium, wherein:
- (i) the aluminum alloy of the body comprises from about 1.3 to about 1.8 wt. % magnesium and from about 0.4 to about 0.8 wt. % manganese;
- (ii) the aluminum alloy of the end comprises from about 4 to about 5 wt. % magnesium and from about 0.4 to about 0.8 wt. % manganese;
- and
- (iii) an absolute value of a difference between the manganese contents of the aluminum alloys is less than 0.1 wt. %.
