Abstract

La présente invention concerne un alliage de moulage à base de Al-Zn-Mg-Cu qui fournit une résistance élevée pour des applications automobiles et aérospatiales et une résistance optimisée à la fissuration par corrosion mécanique dans des environnements hautement corrosifs et de traction. La composition à base de l'alliage selon l'invention comporte entre environ 3,5% en poids et environ 5,5% en poids de Zn; entre environ 1,0% en poids et environ 3,0% en poids de Mg; entre environ 0,5% en poids et environ 1,2% en poids de Cu; une quantité inférieure à environ 1,0% en poids de Si; une quantité inférieure à environ 0,30% en poids de Mn; une quantité inférieure à environ 0,30% en poids de Fe; et le reste étant Al et des impuretés inévitables.
