Production of Aluminum Alloy Sheet Abstract Fine-grained, formable Al-Mn alloy sheet is produced from strip-cast slab (e.g. twin-roll-cast slab) by including 1.3 - 2.3% Mn in the alloy, slab annealing the workpiece by heating it to precipitate most of the Mn in fine intermetallic particles, cold rolling the workpiece to sheet of final gauge with an interanneal performed (between successive cold rolling stages) under nonrecrystallizing conditions to reduce the amount of Mn present in solid solution in the aluminum matrix, and annealing the final sheet.
