Abstract

L'invention concerne des produits d'alliage d'aluminium 7xxx corroyés épais perfectionnés et leurs procédés de production. Les nouveaux produits d'alliage d'aluminium 7xxx peuvent offrir une association perfectionnée de résistance à la fissuration assistée par l'environnement (EAC), et de force, d'allongement et/ou de ténacité à la rupture, entre autres propriétés. Les nouveaux produits d'alliage d'aluminium 7xxx comprennent généralement des quantités élevées de manganèse. Les nouveaux produits d'alliage d'aluminium 7xxx comprennent ainsi généralement de 0,15 à 0,50 % en poids de Mn en association avec 5,5 à 7,5 % en poids de Zn, 0,95 à 2,20 % en poids de Mg et 1,50 à 2,40 % en poids de Cu.
