Abstract (en)
[origin: WO9514113A1] Aluminium-silicon-magnesium alloys having improved ductility and deep-drawing properties for use as sheet or strip, and a method for producing same, are disclosed. The sheet or strip is particularly suitable for deep-drawing and motor vehicle bodywork in particular. The claimed alloy has a chemical composition consisting of: 0.1-0.8 wt % Mn, 0.25-0.8 wt % Mg, 0.5-1.3 wt % Si, up to 0.9 wt % Cu, up to 0.5 wt % Fe, and other elements up to 0.5 wt % each and 0.15 in all, with the balance being Al. The sheet and strip are produced by casting, hot rolling under special reheating and rolling conditions, cold rolling, age-hardening, forming and curing of coatings, and optionally pre-tempering performed between quenching and age-hardening.
