Zusammenfassung:Provided herein is a high-speed blow forming process for shaping aluminum containers using 3xxx can body stock alloys with high recycled content, as well as articles made by that process. A process for shaping aluminum containers as described herein includes the sequential steps of blanking out a disk from a sheet of a 3xxx series aluminum alloy; forming a bottle preform by drawing redrawing, ironing and doming the disk, placing the preform into a mold cavity, applying an axial load to the preform; and injecting an inert gas into the interior of the preform with sufficient pressure until the preform expands to fill the mold cavity.
