Abstract (en)

[origin: WO0140531A1] Aluminum sheets and methods for manufacturing aluminum sheets are provided. The present invention involves control of processing conditions in order to achieve a fine grain size (i.e. ASTM rating of 8.5 or greater) in the material prior to a final cold working operation. Also included within the scope of the present invention are products having a fine grain size which have strength levels above what can be obtained in 5xxx alloys.
