What is the process of manufacturing aluminum strips?

The process of manufacturing aluminum strips involves several key steps. Initially, raw materials, typically bauxite ore, are mined and then processed to extract alumina (aluminum oxide). This alumina is then dissolved in a cryolite bath at high temperatures within a reduction cell in the Hall-H茅roult process. Here, aluminum is reduced and collected as molten metal. The molten aluminum is then cast into ingots or directly into billets. These billets are then hot or cold rolled into strips, with multiple passes through rollers to achieve the desired thickness and width. The strips may undergo annealing to restore ductility and improve workability. Finally, the aluminum strips are cleaned, coated if necessary, and then cut to length, inspected, and packaged for distribution.
