Abstract

L'invention concerne une tôle d'épaisseur 0,5 à 8 mm en alliage à base d'aluminium comprenant, 2,6 à 3,0 % en poids de Cu,, 0,5 à 0.8 % en poids de Li,, 0,1 à 0,4 % en poids de Ag,, 0,2 à 0,7 % en poids de Mg 0,06 à 0,20 % en poids de Zr 0,01 à 0,15 % en poids de Ti optionnellement au moins un élément choisi parmi Mn, V, Cr, Se, et Hf, la quantité de l'élément, s'il est choisi, étant de 0,01 à 0,8 % en poids pour Mn, 0,05 à 0,2 % en poids pour V, 0,05 à 0,3 % en poids pour Cr, 0,02 à 0,3 % en poids pour Se, 0,05 à 0,5 % en poids pour Hf une quantité de Zn inférieure à 0,2 % en poids, une quantité de Fe et de Si inférieure ou égale à 0,1 % en poids chacun, et des impuretés inévitables à une teneur inférieure ou égale à 0,05% en poids chacune et 0,15% en poids au total, la dite tôle étant obtenue par un procédé comprenant coulée, homogénéisation, laminage à chaud et optionnellement laminage à froid, mise en solution, trempe et revenu, la composition et le revenu étant combinés de façon à ce que la limite d'élasticité dans le sens longitudinal Rp0,2(L) soit comprise entre 395 et 435 MPa. La tôle selon l'invention est particulièrement avantageuse pour la fabrication de panneaux de fuselage d'aéronef.
