8xxx Series Aluminium Foil

Flat rolled aluminium is produced by casting aluminium through the melting of aluminium ingots / t-bars. The cast coils are then rolled down to the desired thickness in cold rolling mills. Aluminium foil is produced by rolling mill-finished coils in foil rolling mills down to thicknesses of 0.2 mm or thinner gauges. Aside from foil rolling, the foil production process may also include the annealing, separating, slitting and packaging processes

Flat rolled aluminium below the thickness of 0.2mm is called aluminium foil. 8xxx series are alloyed with other elements which are not covered by other series, typically iron.
