Abstract

La présente invention concerne des produits en alliage d'aluminium et des procédés de fabrication de produits en alliage d'aluminium dans lesquels les produits en alliage d'aluminium ont une densité de particules intermétalliques et une taille de particule soigneusement contrôlées. De tels produits en alliage d'aluminium peuvent présenter une formabilité favorable. La régulation de la taille et de la densité des particules intermétalliques peut permettre l'utilisation de quantités élevées de teneur en source recyclée dans des produits en alliage d'aluminium.
