Abstract

A high strength, aluminum alloy sheet having good formability is disclosed which is particularly suitable for forming can-body parts and can-end parts, which sheet has received a final cold rolling reduction of at least 50% and consists essentially of Mn 0.30 to 1.50 wt. %, Mg 0.50 to 2.00 wt. %, preferably 0.50 to 1.25 wt. %, Si 0.52 to 1.00 wt. % and the balance being Al and incidental impurities. If required, the aluminum alloy forming sheet may also, in addition to the above elements, contain at least one component selected from the group consisting of Fe, Cu, Cr, Zn and Ti in specified ranges. The alloy sheet was produced by a specially prescribed production method.
