What is the process for manufacturing aluminum sheets?

The process of manufacturing aluminum sheets involves several key steps. Initially, raw materials, primarily bauxite, are mined and then processed to extract alumina (aluminum oxide). This alumina is then mixed with cryolite and fed into a reduction cell where it is subjected to a strong electric current, causing the aluminum to be reduced and extracted. The molten aluminum is then poured into molds to cool and solidify into ingots. These ingots are subsequently rolled into sheets in a hot or cold rolling process, where they are gradually reduced in thickness and width. The sheets are then annealed to improve their ductility and strength. Finally, they undergo various finishing processes such as cleaning, coating, or cutting to meet specific requirements before being packaged and shipped to customers.
