Aluminum plays a crucial role in modern industries due to its lightweight and strength. Extracted from bauxite ore, it undergoes the Bayer process to become alumina, then the Hall-Héroult process for electrolytic reduction to pure aluminum. This metal's versatility extends to aerospace, automotive, and packaging, with the added benefit of being recyclable, thus promoting sustainability.
