Abstract

Les alliages d'aluminium peuvent être fabriqués avec un matériau à haute teneur en contenu recyclé, comprenant un matériau recyclé en alliage plaqué mixte (par exemple, un matériau recyclé pré-consommateur à base d'alliage plaqué mixte) et des déchets en fin de vie, et traités pour fournir une résistance et une formabilité élevées. L'invention concerne des alliages d'aluminium qui sont appropriés pour être utilisés en tant que pièces automobiles structurales, même avec une teneur élevée en matériaux recyclés.
