aluminum or aluminium - A silvery-white, ductile metal, having good conductive and thermal properties, and used to form many hard, light, alloys which are corrosion-resistant due to a protective oxide that forms on its surface. Aluminum melts at 1220°F (660.2°C) and can be cast and welded. It is available in a wide variety of colors (possible through a process called anodizing), and is often used in paints, foil, jewelry, and welding and is used when lightness combined with strength is desired. Aluminum is derived from the mineral bauxite. Although bauxite is the most abundant metal in the earth's crust, the processes necessary to creating aluminum were not developed until 1825, and aluminum was not used extensively until the twentieth century.
Atomic symbol Al; atomic number 13; atomic weight 26.98; specific gravity 2.69; valence 3.
This metal, known as aluminum in the United States, is known as aluminium in most other countries.
