Aluminium dat wol 99% suver of heger wurdt suver aluminium neamd. Primêr aluminium, it metaal produsearre yn in elektrolyseofen, befettet in rige fan “ûnreinheden”. Lykwols, yn it algemien, allinnich izer en silisium eleminten boppe 0.01%.
Foar folies grutter as 0.030 mm (30µm), de meast foarkommende aluminium alloy is en aw-1050: suver aluminiumfolie mei op syn minst 99.5% aluminium. (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.
