Zusammenfassung:The present invention provides a heat treatment method of an aluminum alloy panel, which can prevent surface curvature of molded aluminum alloy panel. For this purpose, the present heat treatment methods comprise: cold rolling an aluminum alloy panel at a reduction ratio of 45 to 50% at a final pass in a cold rolling process; first heat-treating the cold-rolled aluminum alloy panel at 450 to 510° C. for 3 hours; rapidly cooling the heat-treated aluminum alloy panel at a rate 60° C./sec or higher after the first heat treatment; and second heat-treating the rapidly cooled aluminum alloy panel at 200 to 220° C.
