Abstract

L'invention concerne des alliages d'aluminium type Al-Si-Mg à ductilité et emboutissabilité améliorées, utilisés sous forme de tôles ou bandes, ainsi qu'un procédé d'obtention de ceux-ci. Les tôles ou bandes sont particulièrement destinées à l'emboutissage et en particulier à la carrosserie automobile. L'alliage revendiqué possède la composition chimique suivante (en poids %): de 0,1 à 0,8 Mn; de 0,25 à 0,8 Mg; de 0,5 à 1,3 Si; jusqu'à 0,9 Cu; jusqu'à 0,5 Fe; jusqu'à 0,5 (chacun) et 0,15 (au total) d'autres éléments; reste Al. Ces tôles et bandes sont obtenues par coulée, laminage à chaud dans des conditions de réchauffage et de laminage particulières, laminage à froid, mâturation, formage et cuisson des revêtements, un pré-revenu étant éventuellement pratiqué entre trempe et mâturation.
