Abstract[English]
Clad aluminum alloy products can include a core layer comprising an AA2xxx series aluminum alloy and cladding layer comprising an AA2xxx series aluminum alloy. The chemistry of each of the AA2xxx series aluminum alloys, especially the Cu content and the Mg content, can be tailored to improve corrosion resistance. Such clad aluminum alloy products may be suitable for structural aerospace parts including use in hydrogen tank applications.[French]
Produits en alliage d'aluminium plaqué pouvent comprendre une couche centrale comprenant un alliage d'aluminium de série AA2xxx et une couche de placage comprenant un alliage d'aluminium de série AA2xxx. La chimie de chacun des alliages d'aluminium de série AA2xxx, en particulier la teneur en Cu et la teneur en Mg, peut être adaptée pour améliorer la résistance à la corrosion. De tels produits en alliage d'aluminium plaqué peuvent être appropriés pour des pièces aérospatiales structurelles, y compris à l'utilisation dans des applications de réservoir d'hydrogène.
