bobina de aluminio is a processed product of aluminum metal, que es aluminio puro combinado con diferentes elementos de aleación para cambiar sus propiedades mecánicas, resistencia a la corrosión, formabilidad, y maquinabilidad. Se convierte en una bobina de aleación de aluminio con buenas propiedades metálicas. Se añaden diferentes elementos de aleación al metal de aluminio., y las bobinas de aluminio obtenidas tienen diferentes características. 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 bobinas de aluminio serie
1000 serie de aleación de aluminio, 2000 serie de aleación de aluminio, 3000 serie de aleación de aluminio, 4000 serie de aleación de aluminio

5000 serie de aleación de aluminio, 6000 serie de aleación de aluminio, 7000 serie de aleación de aluminio, 8000 serie de aleación de aluminio

The aluminum alloy aluminum coils of each of these series are divided into more detailed divisions, como 1100 bobinas de aluminio, 5754 bobinas de aluminio, 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. Para el 1000 serie, these numbers indicate the purity of the alloy.

Por ejemplo, Aluminium Coil 1060 is made of almost pure aluminum and contains 99.60% aluminio.
The following are alloys contained in different series of aluminum coils
1XXX aluminum coil 99.00% aluminio (mínimo)
2XXX aluminum coil cobre
3XXX aluminum coil manganeso
4XXX aluminum coil silicio
5XXX aluminum coil magnesio
6XXX aluminum coil magnesium and silicon
7XXX aluminum coil zinc
8XXX aluminum coil Otros elementos
