Aluminum coil is a metal material widely used in various industrial fields, and its unique properties and wide range of applications make it an indispensable part of many industries. So, what is the raw material of the aluminum coil?

The main raw material of aluminum coil: aluminum ore

The main raw material of aluminum coil is aluminum ore. Aluminum ore is a kind of ore containing aluminum, the most common of which is aluminum silicate ore. These ores are crushed, ground, and extracted by a specific chemical reaction, such as the Bayer process or sintering process.

Other components of aluminum rolls

In addition to aluminum ore, other elements may also be added to the production process of aluminum coils, such as magnesium, silicon, copper, etc., to improve certain properties of aluminum coils, such as strength, corrosion resistance or processability.

Aluminum coil production process

In the process of producing aluminum coils, aluminum ore powder is first fed to an aluminum oxide plant for refining. In the refining process, aluminum oxide is separated from aluminum ore and processed through a series of chemical reactions and processes to finally obtain pure aluminum oxide.

Next, the pure alumina is fed into the electrolytic aluminum plant, where it is converted into liquid aluminum by electrolysis. In the process of electrolysis, aluminum oxide is placed in an electrolytic cell, and after passing direct current, aluminum oxide is electrolyzed into liquid aluminum and oxygen. The liquid aluminum is then sent to a continuous casting machine, where it is cast into aluminum ingots through a continuous casting process.

Finally, aluminum ingots are sent to aluminum processing plants, after heating, rolling and other processes, and finally get aluminum rolls. Aluminum coil has good plasticity, electrical conductivity, thermal conductivity and corrosion resistance, so it has a wide range of applications in construction, automotive, electronics, packaging and other industries.

Sum up

The raw material of aluminum coil is mainly aluminum ore, which is finally converted into aluminum coil through the process of refining, electrolysis, continuous casting and processing. As an important metal material, aluminum coil has a wide range of applications in various fields, and plays an important role in promoting industrial development and improving people's living standards.
