The invention relates to a thin strip or foil, having a thickness of 6 to 200 mkm, preferably, of 6 to 50 mkm, 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 R> 110 MPa for a thickness > 9 mkm and > 100 MPa for a thickness of 6 to 9 mkm, and an elastic limit R> 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. |
