Telescope mirrors are also coated with a thin layer of aluminum. Nearly all modern mirrors are made using a thin reflective coating of aluminum on the back surface of a sheet of float glass. Pure aluminum easily forms alloys with many elements such as copper, zinc, magnesium, manganese and silicon. The use of aluminum exceed that of any other metal except iron. Structural components made from aluminum are vital to the aerospace industry and very important in other areas of transportation and building in which light weight, durability, and strength are needed. Aluminum is used in many industries to make millions of different products and is very important to the world economy. Aluminum is nontoxic (as the metal) nonmagnetic and non-sparking.Īluminum has only one naturally occurring isotope, aluminium-27, which is not radioactive.Ī silvery and ductile member of the poor metal group of elements, aluminum is found primarily as the ore bauxite and is remarkable for its resistance to oxidation (aluminum is actually almost always already oxidized, but is usable in this form unlike most metals), its strength, and its light weight. It has a dull silvery appearance, because of a thin layer of oxidation that forms quickly when it is exposed to air. However, in the USA the preferred name was aluminum and when the American Chemical Society debated on the issue, in 1925, it decided to stick with aluminum.Īluminum is a soft and lightweight metal. Aluminum was the original name given to the element by Humphry Davy but others called it aluminum and that became the accepted name in Europe.
The name aluminum is derived from the ancient name for alum (potassium aluminum sulphate), which was alumen (Latin, meaning bitter salt).
