    Abstract: Process for making high formability aluminium alloy sheets, wherein a sheet of an alloy in which Al is alloyed with Si, Mg, Cu, Mn and Fe and with one or more elements selected from Cr, Zn, Zr and Ti is subjected to a continuous solution treatment process for at least 3 seconds at over 450 DEG C, followed by cooling to a temperature of 60 to 250 DEG C at a rate higher than 100 DEG C/mn, reeling while maintaining the sheet at the temperature of 60 to 250 DEG C, and preageing for a period of 1 minute to 10 hours at said temperature of 60 to 250 DEG C. The object of the invention is to improve the mechanical properties and the formability of aluminium alloy sheets to be used for automotive body components.
