Abstract

La présente invention concerne l'utilisation de zinc comme additif pour limiter ou retarder la corrosion associée à la présence d'une contamination par du nickel (0,004-0,10 % en poids de Ni) dans des alliages d'aluminium. Le Zn est ajouté à des alliages d'aluminium contaminés par du Ni pour obtenir au moins 200 ppm de Zn et jusqu'à 1000 ppm de Zn. L'additif de zinc peut être ajouté à un alliage d'aluminium comprenant, en pourcentage en poids, 6,5-7,5 % de Si, un maximum de 0,2 % de Fe, un maximum de 0,2 % de Cu, un maximum de 0,1 % de Mn, un maximum de 0,2 % de Ti, 0,25-0,45 % de Mg et le reste étant de l'Al et des impuretés inévitables. Un procédé pour limiter la corrosion d'un produit d'aluminium implique l'addition de Zn à un premier alliage d'aluminium contenant entre 0,004-0,10 % en poids de Ni, à une concentration comprise entre 0,02 et 0,1 % en poids, et ensuite le travail de l'alliage pour obtenir le produit.
