Bobine en aluminium is a processed product of aluminum metal, qui est de l'aluminium pur combiné à différents éléments d'alliage pour modifier ses propriétés mécaniques, résistance à la corrosion, formabilité, et usinabilité. Il devient une bobine en alliage d'aluminium avec de bonnes propriétés métalliques. Différents éléments d'alliage sont ajoutés au métal aluminium, et les bobines d'aluminium obtenues ont des caractéristiques différentes. In order to distinguish them, these aluminum coils are classified.

From the forging method, it can be divided into forged aluminum and cast aluminum. Wrought aluminum is produced by smelting an aluminum ingot with a specific amount of alloying metal to produce the desired grade of composition. The smelted aluminum alloy is cast, rolled, forged, extruded, and other mechanical processing processes. In order to distinguish the grades of wrought aluminum, a four-digit code is used to identify each wrought aluminum grade.
The ones we know are: 1-8 bobines en aluminium de série
1000 alliage d'aluminium de série, 2000 alliage d'aluminium de série, 3000 alliage d'aluminium de série, 4000 alliage d'aluminium de série

5000 alliage d'aluminium de série, 6000 alliage d'aluminium de série, 7000 alliage d'aluminium de série, 8000 alliage d'aluminium de série

The aluminum alloy aluminum coils of each of these series are divided into more detailed divisions, tel que 1100 bobines d'aluminium, 5754 bobines d'aluminium, etc. where the first number represents the main alloying element added to pure aluminum. The main alloying elements greatly affect the properties of the grades in the series. The second number refers to the modification of the specific alloy. Modifications are registered with IADS, which requires specific documents. If the specified number is zero, the alloy is pristine or unmodified. The third and fourth digits are arbitrary numbers assigned to specific alloys in the series. Pour le 1000 série, these numbers indicate the purity of the alloy.

Par exemple, Aluminium Coil 1060 is made of almost pure aluminum and contains 99.60% aluminium.
The following are alloys contained in different series of aluminum coils
1XXX aluminum coil 99.00% aluminium (minimum)
2XXX aluminum coil cuivre
3XXX aluminum coil manganèse
4XXX aluminum coil silicium
5XXX aluminum coil magnésium
6XXX aluminum coil magnesium and silicon
7XXX aluminum coil zinc
8XXX aluminum coil Autres éléments
