1. In the past fifty years, aluminum has become one of the most widely used metals in the world. Especially in recent years, aluminum, as an environmental protection material for energy saving and consumption reduction, has been further expanded regardless of the scale of application or the amount of consumption. Especially in the construction industry, transportation industry and packaging industry, the aluminum consumption of these three industries usually accounts for about 60% of the total aluminum consumption in the year.

2. In the construction industry, because of the stability of aluminum in the air and the excellent appearance after anode treatment, aluminum has been continuously added and widely used in the construction industry, especially in aluminum alloy doors and windows, aluminum plastic pipes, decorative panels, The application of aluminum curtain wall, etc.

3. In the transportation industry, in order to reduce the weight of the vehicle itself and reduce the pollution of exhaust emissions to the environment, many transportation vehicles such as motorcycles, various cars, trains, subways, airplanes, and ships have begun to use aluminum and aluminum alloys. Components and fittings. With the continuous improvement of the hardness and strength of aluminum alloy processing materials, the share of applications in the aerospace field has begun to increase year by year.

4. In the packaging industry, the scale of aluminum used in various types of flexible packaging, such as aluminum foil, all-aluminum cans, various bottle caps and easy-open lids, and medicinal packaging, is also expanding.

5. In other areas of consumption, the application and application prospects of electronic and electrical appliances, household appliances (refrigerators, air conditioners), and daily hardware are getting wider and wider.
