The present invention relates to an improved method of producing an aluminum alloy sheet which, in one embodiment, includes roll casting an aluminum alloy strip having a thickness of less than about 0. 5 inch and, subsequently, preferably without intervening thermal treatments or surface cleaning, cold rolling the strip to a thickness of less than about 0. 15 inch, after which the cold rolled strip is subjected to thermal treatment which is preferably either continuous annealing or solution heat treatment. The aluminum alloy, in a continuous annealing embodiment, is preferably selected from the group consisting of the 3XXX and 5XXX series. In another embodiment wherein solution heat treatment is employed, the aluminum alloy is preferably selected from the group consisting of 2XXX and 6XXX. The sheet may be converted into a motor vehicle body panel.

The present invention provides aluminum alloys and layers formed in aluminum alloys as well as methods for their manufacture. Aluminum alloys of the present invention are provided with at least one discrete layer of uncrystallized grains formed therein. Alloys of the present invention can be formed, for example, by a process that includes a final partial anneal that permits softening of the material to essentially an O-temper condition. Processes of the present invention recrystallized substantially the entire material by leave a discrete layer of preferably less than 50 microns of the material unrecrystallized. In preferred embodiments, the aluminum material is a core material that is clad on one or both sides and the discrete unrecrystallized layer forms at the boundary between the clad and the core.

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.
