Aluminium has a melting point of 660.37°C, boiling point of 2467°C, specific gravity of 2.6989 (20°C). Pure aluminium is a silvery-white metal. It is soft, light, relatively nontoxic, with a high thermal conductivity, and high corrosion resistance. It can be easily formed, machined, or cast. Aluminium is nonmagnetic and non sparking. It is second among metals in terms of malleability and sixth in ductility. Aluminium coatings are highly reflective of both visible and radiant heat. The coatings form a thin layer of protective oxide and do not deteriorate like silver coatings.

The biggest use of aluminium is in packing. Electrical transmission is another very big application area for aluminium. Aluminium is also used in the construction industry in the form of window and door frames, cladding, and roofing. Hot and cold rolling processes are used to obtain flat products such as sheets and foil. die, sand, and investment are used to produce castings.
