This paper presents the evolution in characteristics and in applications of high strength Aluminium alloys for aeronautics and aerospace. Such an evolution will be described, after a short introduction, on the basis of the following path: (1). 1925; 1934; 1943. From the pre-Aluminium age in Europa to the top Italian constructions (prototypes of the M C 72 kind) and to the most significant military series constructions: MC205 'Veltro', in the 1939-1942/43 period. (2). 1943-2004. The versatility of the Aluminium alloys after the Second World War (with detailed examples concerning the wings system). The division between the alloys of the first and second generation (mono- and di-isothermal treatments); first constructions using polymeric matrix composites. (3). 1986 -2004. The strategic alliance between Aluminium Alloys and non-metallic matrix composites.. The newconcept aeroplanes and the energy crisis.(Piaggio P180 - ,Avanti') (4).The aerospace constructions and the maximum use of Al alloys for the parts of Saturn Five Stage ('Apollo Program'). (5)(1999 - 2003) The Aluminium aeronautics alloys and the 'second aeronautics': the dies for injection moulding of plastics. The conclusions summarise some of the outstanding results for high strength Al alloys, highlighting the Italian technological victories.
