Aluminium is a light metal which is highly resistant to corrosion. It is used for a wide range of applications such as packaging, ladders, aircraft, vehicles, window frames, etc. Although the production of aluminium (aluminium smelting) uses a large amount of energy the low weight of the metal can lead to a lower energy consumption during the use of a product. The high resistance to corrosion also contributes to the long lifespan of aluminium products. Finally, at the end of their lifespan, aluminium products are easily recycled into new aluminium.
