Aluminium is the youngest of today’s most commonly-used metals despite the fact that bauxite, its unrefined ore, comprises 8% of the earth’s crust making it the 3rd most common element. The first commercial production was developed in 1886, and current annual world production of primary aluminium is now around 26 million tonnes. This makes aluminium the most widely used non-ferrous metal.
Aluminium can be used in a wide variety of applications and forms because of its unique combination of properties, combiningraw bauxite lightness, strength, durability and corrosion resistance with good thermal and electrical conductivity. A wide range of alloys is available to exploit these properties to the full. Its major markets are in transport (road, rail, sea and air), building and construction (from screws to skyscrapers), electrical and mechanical engineering (power transmission, machinery, access equipment) and packaging (food, pharmaceuticals, beverage cans and sealable containers). Aluminium alloys maintain a leading position in these markets by providing the most cost effective solution for many industrial and consumer applications.
