A European consortium is designing a supersonic transport aircraft to replace Concorde for which it is currently proposed to use aluminium alloys for the fuselage. The requirement is for a material that has creep resistance and damage tolerance better than the Concorde alloy 2618A and promising results have been obtained with extruded Al-Cu-Mg-Ag alloys hardened mainly by the Ω precipitate. Data is presented which shows that the tensile properties and creep performance of these alloys are generally superior to that of competing commercial alloys of the 2000 series.
