Principal Metals

Aluminium

• Aluminium metal is result of two processes.
• Bauxite (Aluminium Ore) is refined into alumina, which in turn is electrolytically reduced into aluminium.
• It takes 3 tonnes of bauxite to make one tonne of aluminium.
• The resultant metal is then extruded rolled or cast for use in many applications, eg aerospace, packaging, automotive and construction.
