The resulting extra thin sheets or [of?] foil is then cut up into rolls using special cutters. The material used most often in the production of foil is pure primary aluminium or 1xxx, 3xxx and 8xxxx series aluminum alloys that include iron, silicon, manganese and occasionally copper if greater strength is needed. Heated aluminium is rolled into sheets between 2 and 100 mm thick (hot rolling). These are then cold-rolled into foil of the required thickness.
