Abstract

L'invention concerne un procédé de fabrication d'une tôle mince en alliage à base d'aluminium comprenant, en % en poids, 2,3 à 2,7 % de Cu, 1,3 à 1,6 % de Li, 0,2 à 0,5 % de Mg, 0,1 à 0,5 % de Mn, 0,01 à 0,15 % de Ti, une quantité de Zn inférieure à 0,3, une quantité de Fe et de Si inférieure ou égale à 0,1 % s chacun, et des impuretés inévitables à une teneur inférieure ou égale à 0,05% en poids chacune et 0,15% en poids au total, dans lequel notamment la température d'entrée de laminage à chaud étant comprise entre 400°C et 445°C et la température de sortie de laminage à chaud étant inférieure à 300 °C. Les tôles selon l'invention présentent des propriétés mécaniques avantageuses et sont notamment utilisées pour la fabrication de panneau de fuselage d'aéronef.
