Aluminum alloy having an improved combination of properties are provided. In one aspect, a method for producing the alloy includes preparing an aluminum alloy for artificial aging and artificially aging the alloy. In one embodiment, the arti- ficially aging step includes aging the aluminum alloy at a temperature of at least about 250 °F, and final aging the aluminum alloy at a temperature of not greater than about 225 °F and for at least about 20 hours. These aluminum alloys realize an improved com- bination of properties, including improved strength with at least equivalent fatigue crack growth resistance.

L'invention porte sur un alliage d'aluminium ayant une combinaison améliorée de propriétés. Sous l'un de ses aspects, l'invention porte sur un procédé de fabrication de l'alliage qui comprend la préparation d'un alliage d'aluminium pour un vieillissement artificiel et un vieillissement artificiel de l'alliage. Dans un mode de réalisation, l'étape de vieillissement artificiel comprend le vieillissement de l'alliage d'aluminium à une température d'au moins environ 250°F, et le vieillissement final de l'alliage d'aluminium à une température non supérieure à environ 225°F et pendant au moins environ 20 heures. Ces alliages d'aluminium réalisent une combinaison améliorée de propriétés, comprenant une résistance améliorée avec une résistance au moins équivalente à la croissance de fissure de fatigue.
