Abstract
The object of the invention is a method for manufacturing aluminum alloy strips with a thickness less than or equal to 12 .mu.m, including: elaboration of an alloy with composition (weight %): Si:0.15-0.40 Fe: 1.10-1.70 Mg<0.02 Mn:0.30-0.50 other elements<0.05 each and total<0.15, remainder is aluminum, continuous casting between rolls of a strip of this alloy with a thickness between 2 and 10 mm, homogenization of this strip at a temperature between 450 and 620.degree. C. with a duration between 8 and 40 hrs, cold-rolling of this strip intermediate annealing of this cold-rolled strip to a temperature between 200 and 400.degree. C., and with a duration between 8 and 15 hrs, cold-rolling of the annealed strip up to the final thickness less than or equal to 12 .mu.m, final annealing of the strip at a temperature between 200 and 300.degree. C., with a duration of at least 50 hrs. The method is notably applied to the manufacturing of strips for aseptic food packages of the brick type.
