Description:
Pure aluminium is a silvery-white
metal with many desirable characteristics. It is light, non-toxic (as the
metal), non-magnetic and non-sparking. It can use to be decoration. It is
easily formed, machined, and cast. Pure aluminium is soft and lacks strength,
but alloys with small amounts of copper, magnesium, silicon, manganese, and
other elements have very useful properties. Aluminium is an abundant element
in the earth's crust, but it is not found free in nature. The Bayer process
is used to refine aluminium from bauxite, an aluminium ore.
