Abstract
A method for making aluminum alloy can stock from continuously cast aluminum alloy slabs includes the steps of continuous casting, hot rolling, hot line annealing, cold rolling, intermediate annealing and cold rolling to final gauge. After the material is cold rolled to final gauge, it is subjected to a heat treatment step which improves its formability. The method is suited for improved AA3000 series type alloys. Besides improved formability, the inventive method also provides increased alpha phase content and low earing percentage for improvements in can manufacture. An improved aluminum alloy product also is disclosed.
