Aluminum is a light weight metal so it is important in the transportation industries, for example aircraft, automobiles, ships and trains. The specific gravity of aluminum is 2. This is approximately one third that of iron and copper. It has excellent resistance against corrosion. When exposed to air, thin oxidized film forms on the surface protecting it from corrosion.

Aluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminium through the electrolysis of aluminium oxide Al 2 O 3 , which must first be mined from bauxite ore and then refined using the Bayer process. A common practice since the early s and extensively capitalized during World War II , aluminium recycling is not new.
Aluminum is the most abundant metal in the world and also one of the most recycled a fact that can be attributed to the strong price it commands in worldwide commodities markets. Electrical conductors, transport, packaging, building and architecture, miscellaneous applications such as high pressure gas cylinders, machined components, sporting equipment, road barriers and signs and lithographic plates. The recycling of aluminum provides many environmental and economic benefits.
