  • Aluminum Bronzes

    High aluminum alloys are quenched and tempered. Aluminum bronzes are used in marine hardware, shafts and pump and valve components for handling seawater, sour mine waters, nonoxidizing acids, and industrial process fluids. They are also used in applications such as heavy duty sleeve bearings, and machine tool ways.

  • Extraction Process of Aluminium from Bauxite Ore

    Aluminum is the most abundant metal in the earth's crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes. Bauxite is the general name given to the hydrated oxides of aluminum.

  • How Is Aluminum Extracted From Its Ore?

    Aluminum is extracted from bauxite ore by way of the Bayer process. This requires a great deal of electricity; consequently, a large amount of aluminum is processed in Iceland, which gets its electricity through geothermal energy. To extract aluminum, the bauxite ore is first crushed, then mixed with lime, hot water and soda ash.

  • How Aluminum is Produced

    Aluminum is formed at about 900C, but once formed has a melting point of only 660C. In some smelters this spare heat is used to melt recycled metal, which is then blended with the new metal. Recycled metal requires only 5 per cent of the energy required to make new metal. Blending recycled metal with new metal allows considerable energy
