The density of aluminum is very small, only 2.7g/cm³. Although it is soft, it can be made into various aluminum alloys, such as duralumin, super duralumin, rust-proof aluminum, cast aluminum, etc. These aluminum alloys are widely used in aircraft, automobiles, trains, ships and other manufacturing industries. In addition, space rockets, space shuttles, artificial satellites also use a lot of aluminum and its alloys. A supersonic aircraft, for example, is made up of about 70 percent aluminum and its alloys. Ships also use a lot of aluminum in their construction. A large passenger ship often uses several thousand tons of aluminum.
Aluminum's light weight and corrosion resistance are two outstanding characteristics of its performance.
1. The density of aluminum is very small, only 2.7g/cm³. Although it is soft, it can be made into various aluminum alloys, such as duralumin, super duralumin, rust-proof aluminum, cast aluminum, etc. These aluminum alloys are widely used in aircraft, automobiles, trains, ships and other manufacturing industries.

A large passenger ship often uses several thousand tons of aluminum.
2, the electrical conductivity of aluminum is second only to silver, copper and gold, although its conductivity is only 2/3 of copper, but the density is only 1/3 of copper, so the transmission of the same amount of electricity, the quality of aluminum wire is only half of copper wire. The oxide film on the surface of aluminum not only has the ability of corrosion resistance, but also has certain insulation, so aluminum has a wide range of uses in the electrical manufacturing industry, wire and cable industry and radio industry.
3, aluminum is a good conductor of heat, its thermal conductivity is 3 times larger than iron, industrial aluminum can be used to manufacture a variety of heat exchanger, heat dissipation materials and cookware.
4, aluminum has good ductility (its ductility is second only to gold and silver), at 100℃ ~ 150℃ can be made into thin 0.01mm aluminum foil. These aluminum foil is widely used in packaging cigarettes, candy, etc., can also be made into aluminum wire, aluminum strips, and can roll a variety of aluminum products.
5, because of the dense oxide protective film on the surface of aluminum, not susceptible to corrosion, often used in the manufacture of chemical reactors, medical equipment, refrigeration units, oil refining units, oil and gas pipelines, etc.
6, aluminum powder with silver luster (general metal in powder color is black), commonly used to do paint, commonly known as silver powder, silver paint, in order to protect iron products from corrosion, and beautiful.

In order to improve the rolling efficiency and the quality of aluminum foil products, modern aluminum foil rolling mill is developing to four directions: large roll, wide width, high speed and automation. The width of the roll body of contemporary aluminum foil mill has reached more than 2200mm, the rolling speed has reached more than 2000m/min, and the rolling weight has reached more than 20t. The corresponding level of mill automation has also been greatly improved, and thickness control systems (AGCs) are commonly installed, most of which are plate shape meters (AFCs). Aluminum foil industry is facing a period of rapid development.

Technical term for aluminum sheet
Drawing aluminum plate: The manufacturing process of repeatedly using sandpaper to scrape the aluminum plate out of the line, the main process is divided into three parts: deester, sand mill, washing. In the drawing process of aluminum plate, the special skin film technology after anode treatment can generate a skin film containing the metal composition on the surface of aluminum plate, and clearly show each fine wire trace, so that the fine hair luster in the metal matte.
