alcohol, with that dissolves in water in specific forms. Good conductors of heat and electricity. Yield strength of pure aluminum is 7-11 megabytes Backsl, while the aluminum alloy with a yield strength ranging from 200 to 600 MPa and aluminum about one-third the density and stiffness of steel, a retractable and roads where you can mold it relatively easy. Return excellent aluminum's ability to resist corrosion to the thin surface layer is porous and bonded aluminum oxide which is formed when the metal is exposed to air, which prevents the continuation of the process of oxidation. Stronger aluminum alloy to be less resistant to corrosion due to galvanic reactions with copper alloys. This corrosion resistance usually Matnkhvd significantly reduced when there are several salt solutions, in particular the existence of different metals. Have aluminum atoms in the face-centered cubic structure (fcc).
Aluminium one of the few metals that keeps the full reflection silver when they are accurately powder, which makes it a very important component in the silver coatings. And higher aluminum mirror reflection of any metal at wavelengths (200-400 nm) (in the field of UV) and at 3000-10000 nm (in the infrared), while tin and silver excel in the field of visible light 400. 700 nm and the silver, gold, copper excel in the field of wavelength 700 * 3000.
Aluminum is a good conductor of heat and electricity, and weighs less than copper. Aluminum can be connected to a superior degree with a critical temperature of 1.2 Kelvin ultra-connected, a critical magnetic field of about 100 Gauss
The presence of aluminum in natureAluminum metal or aluminum metal is one of the most abundant elements in the earth's crust after oxygen and silicon by the amount of 8.3%.
No Ewagd aluminum metal in nature in pure form free, is due to draw strong aluminum for oxygen, so in oxides or silicates, feldspar, which are more common in the earth's crust are the metals aluminum silicate groups. Can the original aluminum metal as a case that there are secondary in low oxygen environments, such as inside some volcanoes. There are also aluminum metal in metals beryl, cryolite, Algarani, Alaspinl, turquoise. Impurities in aluminum oxide, such as chromium or cobalt gives gems such as rubies, pure aluminum oxide known as Alchorond, is one of the hardest known material at all with that aluminum is a common and widespread element and on a large scale, but the metals aluminum is not considered economic confiscated for the metal. Almost all aluminum metal produced from ore Albuxt AlOx (OH) 3-2x and there are large amounts of bauxite in Australia, Brazil, rich, Jamaica, but the main ore mines are in Ghana, Indonesia, Jamaica, Russia and Suriname. And fused ore mainly in Australia, Brazil, Canada, Norway, Russia and the United States. Because the smelting process is energy-intensive process, the areas where the natural gas supply increases (such as Arab Emirates) have become places of refining aluminum.
