Aluminum, also known by its element symbol Al, is the most widely used non-ferrous metal in the world

Aluminum takes up 8% of the Earth's surface and it is the third-most copious element. However, aluminum cannot be obtained in metal form in nature. Aluminum was first resolved as a metal in Germany in 1827 and became industrialized for the first time in 1955 by France, who discovered the method of electrolysis. In 1966, electrolysis methods for mass-production was perfected and soon became the foundation for the light-alloy era. Nowadays, the raw material of aluminum is bauxite. Common methods of making aluminum is to electrolyze alumina, which was made by bauxite.

Aluminum is a soft, silver-white material that has outstanding malleability and ductility. It is processed into various forms such as planks, foils, rods, wires, and pipes, which are then used in aircrafts, vessels, railways, as well as in power cables (as a good, lightweight conductor). And because of aluminum's resistance to corrosion and its non-toxicity to the human body, it is used for the packing and storing of food and beverages, as well as many uses in the automotive and architectural fields.
