Abstract

La présente invention concerne des produits d'alliage d'aluminium de série 7xxx corroyés améliorés. Les produits d'alliage d'aluminium de série 7xxx corroyés comprennent généralement de 6,0 à 10,0 % en poids de Zn, de 1,4 à 2,2 % en poids de Mg, de 1,3 à 2,5 % en poids de Cu et de 0,080 à 0,250 % en poids de Cr. Les produits d'alliage d'aluminium de série 7xxx corroyés améliorés ont généralement une épaisseur allant de 3,0 pouces à 12 pouces et présentent un ensemble amélioré de propriétés, par exemple un ensemble amélioré de résistance à la déviation des fissures, solidité, ténacité et résistance à la corrosion.
