Aluminium is the most common metal in the Earth's crust of the Earth and the silvery white. Aluminium is known and also because of the low density and corrosion. Corrosion resistance is caused by a thin layer of aluminium oxide that forms when it is exposed in the air of metal; it is not magnetic and spark free and dissolved in alcohol. Aluminium is a good thermal and electrical conductors.
Aluminium Density is extracted from iron ore, bauxite, which is extracted with techniques. Bauxite is purified with Bayer process.
The extensive use of aluminium is the metal versatility. Its low weight, good thermal and electrical conductivity, plasticity, resistance to traction, high Reflectivity, etc. are suitable for use in the construction of housing for aircraft, electrical cable of containers for the storage of food and many others. Many commercial and military aircraft are made primarily of aluminum. Metal makes time sheets for coatings, wheels, air conditioning, automatic transmission, engine blocks and radiators. In addition, the transfer of the skins, engines for aircraft, landing, furniture and aluminum frame.
It is made from aluminium slightly in the sheets at different levels, in the role of thick aluminum, shapes, sheets, rods, tubes and very malleable wires. And not to lose temperature extremes, and it is readily recyclable. Also it has reflective properties and is used in the center of attention in infrared hair dryer, heating, lighting, and waveguide. It is used as insulating material in buildings due to its characteristics of heat and light.
Aluminium Density in the form of a fine powder, found in a variety of fuel for rockets, explosives and chemical agents sink that is used. Most modern mirrors consist of a thin layer of reflective aluminium in the float of rear glass. The telescope mirrors are also good capacity reflective coating of aluminium.
Friedrich Wöhler was first to isolate the metal in 1827. But the metal is used since time immemorial. Although it was not isolated until the 19th century, was by the Romans as Schlichtemittel, and they express to carry aluminum wound that uses.
Aluminium has no known function in living cells and produce also known in higher concentrations of toxic effects. You can get stored in the bones and the central nervous system and compete with the absorption of calcium. In very high doses, neurotoxicity, and is well known that the blood-brain barrier to change behaviour. Allergic are experiencing them, Dermatitis, digestive disorders, pain in legs, muscle weakness, anaemia, aluminium, iron absorption is reduced seizures, retardation of growth in children, spinal deformity, etc. Antiperspirants containing aluminum may increase the risk of breast cancer and has aluminium is a factor in Alzheimer's disease, although no evidence has been mentioned.
