Aluminum, is a chemical element. Its chemical symbol is Al, its atomic number is 13. Aluminum element in the earth's crust after oxygen and silicon content, ranking third, is the content of the crust of the most abundant metallic element. In the metal species, second only to steel, the second largest category of metal. To the 19th century, aluminum only emerge as a competitive metal in engineering applications, and rage. Three important developments in aviation, construction, automotive industry, require the material properties of aluminum and its alloys with unique properties, which greatly benefit the production and application of this new metal aluminum. Aluminum is extensively used.
Pure aluminum is soft, not strength, with good ductility, can be pulled into filaments and rolled into a foil, a large number for the manufacture of wire, cable, radio industry and packaging industry. Its conductivity is about two-thirds of the copper, but only one-third the density of copper, and thus, the quality, etc., and so compared to the length of the aluminum and copper, the copper conductivity of aluminum is approximately twice, and the price is lower than that of copper.
Aluminum alloy is the general term for the aluminum-based. The main alloying elements are copper, silicon, magnesium, zinc, manganese, minor alloying elements are nickel, iron, titanium, chromium, lithium and so on.
Aluminum density is low, but the intensity is relatively high, close to or exceed the high quality steel, plastic can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, second only to the use of steel.
