ALLIAGE D'ALUMINIUM À HAUTE DUCTILITÉ, SEMI-RIGIDE DESTINÉ À LA FABRICATION DE DEMI-PRODUITS OU DE PIÈCES POUR VÉHICULES AUTOMOBILES

摘要

The invention relates to an aluminum alloy for producing semi-finished products or components of motor vehicles, a method for producing a strip from an aluminum alloy according to the invention, a corresponding aluminum alloy strip or sheet and a structural part of a motor vehicle consisting of an aluminum alloy sheet. The object to provide an aluminum alloy for the production of semi-finished products or components for motor vehicles, which is highly deformable, medium-strength and very resistant to corrosion,is achieved by an aluminum alloy for the production of semi-finished products or components of motor vehicles, which has the following alloy constituents in% by weight:0.6% ‰ ¤ ¤ ¤ 0.9%,0.6% ‰ ¤ Fe ‰ ¤ 1.0%,Cu ‰ ¤ 0.1%,0.6% ‰ ¤ Mn ‰ ¤ 0.9%,0.5 ‰ ¤ Mg ‰ ¤0.8%,Cr ‰ ¤ 0.05%,Rest Al and impurities, individually not more than 0.05 wt .-%, in total not more than 0.15 wt .-%.
