Many people often think that the crust of iron Fe is the most metals. In fact, most of the earth's crust metal is aluminum Al, followed by the iron, aluminum, accounting for 7.45% of the total weight of the entire crust, almost twice as much of iron! Everywhere on earth compounds of aluminum, like ordinary soil, it contains many of alumina Al2O3. The most important aluminum ore bauxite ore and is alum. China has very rich bauxite.

Aluminum is a silver-white light metal (specific gravity is only 2.7). People often call aluminum "fine steel." Pure aluminum is soft and can be pressed into a thin foil.Nowadays, the bags of candy and cigarettes are mostly "silver paper".Due to the advantages of well conductivity and lightweight, people used aluminum to replace the copper wire manufacturing, especially in long-distance power transmission. The use of aluminum instead of copper wire, poles and other equipment can be reduced. Since the Great Proletarian Cultural Revolution, China overcomed the technical difficulties and developed " to replace copper by aluminum".  The key technology - the aluminum welding technology helped us to produce a variety of aluminum-horsepower motor, saving a lot of copper . Aluminum is also used extensively for chemical, semiconductor and electronics research and optical equipment production. Aluminum can well reflect light, so searchlight shade often used to make aluminum.
