The aluminum oxide (alumina) was used for the first time in 6000. C., in Persia, in the manual production of clay pots and containers, but the presence of the material was still unknown. In 1809, Humphrey Davy was able to prove the existence of aluminum and, in 1821, the French P. Berthier discovered in southern France a reddish ore containing 52% aluminum oxide, bauxite, aluminum ore more common. Finally, in 1825, the Danish physicist Hans Christian Oersted can isolate the aluminum, resulting in the form, as it is known today. In 1886, it became public the process of getting the aluminum, allowing the establishment of the global aluminum industry.
Widely used in industry, aluminum has among its main features:
- high resistance;
- electrical and thermal conductivity;
- corrosion resistance;
- recyclability (aluminum is infinitely recyclable);
All this allows its use in diverse segments such as transportation, packaging, construction, automotive, power transmission, among others.
