Aluminum or Aluminium is a flexible metal in silvery-white color. Aluminium is obtained from bauxite. The process to create aluminum was developed in 1825. Aluminium is used to form several corrosion-resistant alloys. The corrosion-resistant character is due to the formation of a protective oxide on the surface of the metal. Aluminium is a good conductor of heat and electricity. The melting point of aluminium is 1220ºF and hence it can be welded and casted. Anodizing process helps in giving different colors to this metal. Aluminium is used to make jewelry, paints, foil and in welding. Aluminium is a light weight metal with great strength. The extensive use of aluminium began in the 20th century. In United States it is known as aluminum. Hans Coray's Landi Chair, R. Buckminster Fuller's Dymaxion Dwelling Machine etc are few works in aluminium.
