Abstract

Sont divulgués de nouveaux alliages d'aluminium 7xxx. Les nouveaux alliages d'aluminium 7xxx peuvent comprendre 5,0 à 9,0 % en poids de Zn, 1,30 à 2,05 % en poids de Mg, 1,10 à 2,10 % en poids de Cu, avec 2,55 ? (% en poids de Cu + % en poids de Mg) ? 3,85, (i) 0,03 à 0,40 % en poids de Mn et/ou 0,02 à 0,15 % en poids de Zr, avec 0,05 ? (% en poids de Zr + % en poids de Mn) ? 0,50, jusqu'à 0,20 % en poids de Cr, jusqu'à 0,20 % en poids de V, jusqu'à 0,20 % en poids de Fe, jusqu'à 0,15 % en poids de Si, jusqu'à 0,15 % en poids de Ti et jusqu'à 75 ppm de B, le reste étant de l'aluminium, des éléments secondaires et des impuretés. Les nouveaux alliages d'aluminium 7xxx peuvent se présenter sous la forme d'un produit en tôle d'alliage d'aluminium 7xxx ayant une épaisseur de 0,5 à 4,0 mm et comprenant au moins 15 % en volume de grains recristallisés. Les nouveaux alliages peuvent présenter une combinaison améliorée d'au moins deux propriétés parmi la résistance, l'allongement, le comportement à la rupture et la résistance à la corrosion.
