Aluminij tj 99% čisti ili viši naziva se čisti aluminij. Primarni aluminij, metal proizveden u peći za elektrolizu, sadrži niz “nečistoće”. Međutim, općenito, samo elementi željeza i silicija prelaze 0.01%.
Za folije veće od 0.030 mm (30µm), najčešća aluminijska legura je en aw-1050: čista aluminijska folija s najmanje 99.5% aluminij. (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.
