  • Aluminium Smelting


    Pure aluminum is a relatively soft, silvery white metal with a dull luster.

    Aluminum’s great versatility stems from its excellent properties. It is exceptionally light with a density of 2.7g/ccm (by comparison steel has a density of 7.75g/ccm); has great strength when alloyed; is impervious to rust; and possesses a high degree of conductivity.

    Aluminium is also ductile, that is, it can be drawn into wires or pressed into sheets or foil making the metal exceptionally versatile.

    The Hall- Héroult process is the main method of smelting aluminium used today, and consists of five steps: adding bath and alumina; anode; electrolysis; tapping; and primary casting.
