Abstract
A method of making aluminum alloy sheet in a continuous in-line process is provided. A continuously-cast aluminum alloy strip is optionally quenched, hot or warm rolled, annealed or heat-treated in-line, optionally quenched, and preferably coiled, with additional hot, warm or cold rolling steps as needed to reach the desired gauge. The process can be used to make aluminum alloy sheet of T or O temper having the desired properties, in a much shorter processing time.
