1. A method for producing rolled aluminum alloy articles, comprising:
providing a molten aluminum alloy;
continuously casting an aluminum alloy article from the molten aluminum alloy;
reheating the aluminum alloy article after continuously casting, wherein the reheating the aluminum alloy article comprises reheating the aluminum alloy article to a peak metal temperature from 420° C. to 580° C. and maintaining the peak metal temperature for a duration consisting of 1 minute to 5 minutes;
quenching the aluminum alloy article after continuously casting with a quenching device; and
after quenching and reheating, rolling the aluminum alloy article at a rolling temperature from 300° C. to 580° C. to a gauge of 4 millimeters (mm) or greater to produce a rolled aluminum alloy article.
