The most abundant ore of aluminum is bauxite ore. Aluminum has vast applications and is considered to be the most wide used material in all types of engineering. The property of aluminum which makes it suitable for use in various different kinds of engineering applications is its low density and ability to resist corrosion. The ability to resist corrosion is actual through forming a thin layer of aluminum oxide on the rear of aluminum which makes it a motionless material as aluminum oxide is a very less reactive. This phenomenon of placing a layer of oxide on the surface of a metal is known as passivation. The light weight of aluminum makes it useful in aerospace diligence and the use of aluminum cladding is also getting popularity in architectural and construction industry.
