ABSTRACT:
The present invention relates to an improved method of producing aluminum alloy can body stock and can end stock which are particularly suitable for use in manufacturing aluminum alloy can bodies and ends for can bodies. The method for can body stock includes roll casting an aluminum alloy strip having a thickness of less than about 1 to 5 mm and, subsequently, batch annealing the strip, followed by cold rolling, continuous annealing, quenching and cold rolling to desired gauge. The aluminum alloy sheets may then be employed in manufacturing aluminum alloy can bodies. The process produces aluminum alloy sheet having an improved combination strength and caring properties with acceptable surface characteristics. Unique aluminum alloys usable in the claimed processes are also disclosed. In another embodiment, can ends are made by roll casting, followed by cold rolling preferably without prior thermal treatment, continuous annealing, quenching and cold rolling to the desired gauge.
