Abstract
Non-galling, low earing can stock suitable for deep drawing and wall-ironing into can bodies is prepared from continuously cast aluminum alloy strip of an inch or less in thickness. The strip material is heated to a temperature of from 950.degree. to 1150.degree. F. for a time sufficient to homogenize the alloy. The homogenized strip material is cold rolled to effect a first reduction in sheet thickness of at least 25%. The cold rolled sheet is heated to a recovery temperature of up to about 550.degree. F., and subjected to a second cold rolling to effect a reduction in thickness of up to 50%. The cold rolled sheet product is heated to the recrystallization temperature and then subjected to effect a final reduction in thickness of at least 50% of the original thickness of the sheet to impart an H19 temper to the sheet.
