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.
