It has the symbol Al, and its atomic number is 13. It is not soluble in water under normal circumstances. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal, in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface. Aluminium metal is too reactive chemically to occur natively. Instead, it is found combined in over 270 different minerals. The chief ore of aluminium is bauxite. Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates... Physical Aluminium is a soft, durable, lightweight, ductile and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. Aluminium is nonmagnetic and does not easily ignite. A fresh film of aluminium film serves as a good reflector (approximately 92%) of visible light and an excellent reflector (as much as 98%) of medium and far infrared radiation. The yield strength of pure aluminium is 7--11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium has about one-third the density and stiffness of steel. It is easily machined, cast, drawn and extruded. Corrosion resistance can be excellent due to a thin surface layer of aluminium oxide that forms when the metal is exposed to air, effectively preventing further oxidation. The strongest aluminium alloys are less corrosion resistant due to galvanic reactions with alloyed copper. This corrosion resistance is also often greatly reduced when many aqueous salts are present, particularly in the presence of dissimilar metals. Aluminium atoms are arranged in a face-centered cubic (fcc) structure. Aluminium has a stacking-fault energy of approximately 200 mJ/m2... Aluminium mirror finish has the highest reflectance of any metal in the 200--400 nm (UV) and the 3,000--10,000 nm (far IR) regions; in the 400--700 nm visible range it is slightly outperformed by tin and silver and in the 700--3000 (near IR) by silver, gold, and copper. Aluminium is a good thermal and electrical conductor, having 59% the conductivity of copper, both thermal and electrical. Aluminium is capable of being a superconductor, with a superconducting critical temperature of 1.2 Kelvin and a critical magnetic field of about 100 gauss (10 milliteslas)... Aluminium forms strong chemical bonds with oxygen. Compared to most other metals, it is difficult to extract from ore, such as bauxite, due to the energy required to reduce aluminium oxide (Al2O3)... Aluminium electrolysis with the Hall-Héroult process consumes a lot of energy, but alternative processes were always found to be less viable economically and/or ecologically... In 2005, the People's Republic of China was the top producer of aluminium with almost a one-fifth world share, followed by Russia, Canada, and the USA, reports the British Geological Survey... http://en.wikipedia.org/wiki/Reynolds_Group_Holdings The Reynolds Metals Company was founded in 1919 as the U.S. Foil Company in Louisville, Kentucky by Richard S. Reynolds, Sr., a nephew of tobacco king R. J. Reynolds. Initially, the new company supplied lead and tin foil wrappers to cigarette and candy companies. In 1924, the U.S. Foil purchased the manufacturer of Eskimo Pies, which were wrapped in foil. In 1928, Reynolds purchased Robertshaw Thermostat, Fulton Sylphon, and part of Beechnut Foil, adding them to U.S. Foil to create Reynolds Metals. In 1931 the company headquarters was moved to New York City and in 1938 the headquarters was moved again to Richmond, Virginia. The company began producing aluminum foil for packaging in 1926.
