Aluminum alloys are divided into groups, which short description is presented below:

1xxx are almost pure aluminum alloys (99%). These alloys are very light used to manufacture products that are used indoors (for example notebook tables, refrigeration rooms inner walls etc.). The most common alloy – 1050. Can be tempered.

2xxx is aluminum and copper alloy. Can withstand different levels of tempering. Was used widely in planes manufacturing also called – duralumin. However, because of low corrosion resistance and cracking was replaced by 7xxx group alloys.

3xxx is aluminum and manganese alloy. Can be tempered. Is known for having good rusting resistance, can be rolled up, easily processed. Widely used in facade panels and roof tin manufacturing.

4xxx is an aluminum and silicone alloy also called silumin. Is a less common alloy, used to manufacture products that would be hard to deform. The material is known for being stiff, hard to form.

5xxx is an aluminum and magnesium alloy. All alloys belonging to this group are known for good rusting resistance, easy to weld. Alloys are most commonly used in ship building. The most common alloys – 5005, 5754, 5083.

6xxx are aluminum, magnesium and silicone alloys. Easily processed material, also easy to weld, can be tempered. It is the most commonly used aluminum, used to manufacture profiles, pipes, rods, and other products. The most common alloys of this group are 6060, 6082.

7xxx is an aluminum and zinc alloy. Zinc allows to achieve the highest degree of material hardness through tempering compared to other materials.

8xxx is described as an alloy of aluminum and other materials that were not mentioned above. It can be aluminum and lithium alloy, used in electronic industry or other metal alloys.

General aluminum qualities: is a very light metal (almost 3 times less dense material than steel); there is a wide variety of alloys, which helps in choosing the most optimal alloy; recyclable; can be tempered; is rusting resistant, can be easily processed, can be welded, painted, anodized.

Extruding - is a special type of aluminum profile manufacturing, theoretically allowing to form the material to any possible shape or form. Because of the primary softness of aluminum, long aluminum products (pipes/profiles) are manufactured through the process of extruding – by pressing the material through specially made form. Later the products are hardened until they achieve the desired level of hardness. Market diversity calculations show that presently there are more than 20 thousand different aluminum profile forms (window profiles, special system profiles, etc.). Extruding technology allows to create a specific aluminum form desired by the client and to create a required specification product using that form rather cheaply.

Most common aluminum alloy forms: sheets, corrugated sheets, bands, round pipes, square – rectangular pipes, U – profiles, special profiles, angles, rods.
