What is the production process of aluminum sheet?

The production process of aluminum sheets involves several key steps. Initially, raw materials, primarily bauxite, are mined and then refined to produce aluminum oxide. This aluminum oxide is then reduced to aluminum metal through the Hall-H茅roult process, where it is dissolved in molten cryolite and electrolyzed. Once the aluminum is produced, it is heated and cast into large ingots. These ingots are then hot or cold rolled into sheets, which are progressively reduced in thickness. The sheets may undergo further processing such as annealing to improve ductility or coating for specific applications. Quality control checks are performed throughout the process to ensure the sheets meet the required specifications. The final product is then cut to size and packaged for distribution to various industries.
