Aluminium hiyo ni 99% safi au ya juu inaitwa alumini safi. Alumini ya msingi, chuma kinachozalishwa katika tanuru ya electrolysis, ina mfululizo wa “uchafu”. Hata hivyo, kwa ujumla, vipengele vya chuma na silicon pekee huzidi 0.01%.
Kwa foils kubwa kuliko 0.030 mm (30µm), aloi ya kawaida ya alumini ni en aw-1050: foil safi ya alumini na angalau 99.5% alumini. (Aluminum larger than 0.300mm is usually called aluminum strip or aluminum plate.).
Aluminium foil is usually pure aluminum (99–99.9% aluminum content). The so-called pre-rolled strip is approx. Aluminum foil with a thickness of 0.6–1.5 mm is cold rolled to the desired thickness in several rolling steps (passes).
When producing very thin foils, two layers are rolled. This has two different surfaces (glossy and matt). The reason is that the outer surface is in contact with the polishing machine and thus becomes relatively smooth (glossy). In contrast, the inner surface is slightly rough due to free-forming, so due to strong forming, the aluminum hardens during rolling, which means that the aluminum becomes more and more the harder. Subsequent soft annealing makes it soft and flexible again.
