In recent fifty years, aluminum has become one of the most widely used metals in the world. Especially in recent years, as an energy-saving and consumption-reducing environmental protection material, aluminum has been further expanded in both application scope and dosage. Especially in the construction, transportation and packaging industries, the aluminum consumption of these three industries generally accounts for about 60% of the total aluminum consumption in that year.

In the construction industry, due to the stability of aluminum in air and excellent appearance after anodic treatment, aluminum is more and more widely used in the construction industry, especially in aluminum alloy doors and windows, aluminum plastic pipes, decorative plates, aluminum curtain walls and so on.

In the transportation industry, in order to reduce the weight of vehicles and reduce the environmental pollution caused by exhaust emissions, motorcycles, various cars, trains, subways, airplanes, ships and other means of transportation began to use aluminum and aluminum alloys as parts and decorative pieces. With the continuous improvement of hardness and strength of aluminum alloy processing materials, the proportion of aluminum alloy processing materials used in aerospace field began to increase year by year.

In the packaging industry, the application scope of aluminum in various soft packages, all-aluminum cans, various bottle caps and lids and medical packaging is also expanding.

In other consumption fields, the uses and prospects of electronic appliances, household appliances (refrigerators, air conditioners) and daily-use hardware are increasingly broad.
