3xxx 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. 3xxx series alloys contain manganese as the main alloying element.
