Abstract: The invention relates to a thin strip or foil, having a thickness of 6 to 200 ?m, preferably, of 6 to 50 ?m, and composed of an alloy containing (in weight %) Si: 1.0 to 1.5, Fe: 1.0 to 1.5, Cu <0.2, Mn <0.1, other elements <0.05 each up to a total <0.15, the remainder being Al. The annealed thin strip or foil has a tensile strength Rm >110 MPa for a thickness >9 ?m and >100 MPa for a thickness of 6 to 9 ?m, and an elastic limit R0.2 >70 MPa. Preferably, said alloy has a silicon content of 1.1 to 1.3% and an iron content of 1.0 to 1.2%. The aforementioned thin strips or foils may be used especially for the production of multilayer composites, overcaps for bottles or aluminium wrappings.

Abstract: Aluminum alloy strips which are 30-150 m? thick, having a composition (in wt. %): Si<0.4; Fe: 1.5-1.9; Mn: 0.04-0.15; other elements: <0.05 each and 0.15 in total, remainder aluminum. The strips are used, in particular, for the manufacture of trays and dishes for the distribution of foodstuffs and fast food.
