The Aluminum is a chemical element, symbol Al and atomic number 13. It is a non-ferromagnetic metal. Aluminum is third most common element found in the terrestrial crust. Aluminum compounds makeup 8% of the earth's crust and are present in most rocks, vegetation, and animals. 1 In the natural state, it is found in many silicates (feldspar, plagioclase, and micas). As metal is extracted only from the mineral known as bauxite, By the first transformation into alumina by the Bayer process and then in aluminum metal by electrolysis. This metal has a combination of properties that make it very useful in materials engineerings, such as its low density (2700 kg / m³) and its high resistance to corrosion. By alloys suitable can significantly increase their mechanical strength (up to 690 Mpa). It is a good conductor of electricity and heat; it is easily machined and very cheap.
