Description

BACKGROUND OF THE INVENTION

Field of the Invention

This invention relates to aluminum alloy compositions that include at least 50% recycled content, aluminum alloy sheets produced from aluminum alloy compositions that include at least 50% recycled content, and methods of making the aluminum alloy sheet and aluminum packages.

Technical Considerations

Aluminum alloys are widely used in the manufacture of aluminum containers, such as beverage cans and food cans. These aluminum alloys must be formable enough and strong enough to withstand the processes for forming the final aluminum container, the processes for food processing within the container, and distribution.

Aluminum containers and aluminum scrap from industrial processes can be recycled and used to prepare other aluminum products. For example, used beverage can (UBC) scrap is aluminum scrap that is collected from used beverage cans, and can include a mixture of several different aluminum alloys. Aluminum scrap from industrial processes, such as from building, transportation, and printing processes, can also be recycled. Like UBC, scrap from industrial processes can also include a mixture of several different aluminum alloys. The aluminum scrap from UBC and industrial processes can be combined, processed, melted, and then used for producing new aluminum products. However, this aluminum scrap can include impurities and/or undesirable amounts of alloying components.

SUMMARY OF THE INVENTION

To achieve the appropriate balance of alloying components, material strength, and formability, aluminum scrap can be combined with sufficient amounts of prime aluminum and alloying elements. It would be desirable to produce an aluminum alloy composition that uses high amounts of aluminum scrap material and low amounts of prime aluminum and alloying elements that can be used to form an aluminum alloy sheet that meets the formability and strength requirements for manufacturing and processing aluminum containers.
