Aluminum (aluminum in American and Canadian English) is a chemical element that has an atomic symbol Al and atomic number 13. It has a density that is lower than the density of other metals, at approximately one-third of the density of steel. It has a great affinity to oxygen and forms a protective layer of oxide on its surface when exposed to oxygen. Aluminium visually resembles silver, in both its color and in its capacity in reflecting light. Aluminum is soft, magnetic, and ductile. It has one stable isotope 27Al; this isotope has a high frequency, making aluminum the 12th most popular element found in the Universe. The radioactivity of 26Al is used to radiodate. Chemically, it is a post-transitional metallic element within the boron family. As is normal for this group, it creates compounds mostly in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as this, it has polarizing properties, and bonds aluminium forms tend to have covalent. The strong affinity towards oxygen is the reason for aluminium’s frequent relationship with oxygen as oxides; for this reason the presence of aluminium in the Earth primarily in rocks in the crust, which is the third most abundant element after oxygen and silicon, rather than in the mantle. It is never as a free metal.

The discovery of aluminium was announced on 1825 Danish physicist Hans Christian Orsted. The first industrial production of aluminum was started by French chemist Henri Etienne Sainte-Claire Deville in 1856. The availability of aluminium increased to the public with the Hall-Heroult process , which was developed from French engineer Paul Heroult and American engineer Charles Martin Hall in 1886 and the manufacturing of large quantities of aluminium has led to its wide use in industries and in everyday life. Through World Wars I and II aluminum was a vital source of strategic power for aviation. The year 1954 saw aluminium become the most popular aluminium extrusion manufacturers in india.. The 21st century most aluminium was consumed in construction, transportation, engineering and packaging across and around the United States, Western Europe, and Japan.

Despite its presence throughout the world, no living organism is known to use metal salts to make energy, however it is accepted by both animals and plants. Due to the high concentration of these salts, the possibilities to play a role in biology for them is of constant research, and ongoing studies. Read Also : steel rate per kg hyderabad
