Aluminium (symbol Al, atomic number 13) is a silvery-white, lightweight, nonmagnetic metal known for its high strength-to-weight ratio, corrosion resistance, and excellent thermal and electrical conductivity. It is extensively used in aerospace, construction, transportation, packaging, and electrical industries. Produced primarily from bauxite ore through the Bayer and Hall-Héroult processes, aluminium is also highly recyclable, requiring only a fraction of the energy for recycling compared to primary production. Its versatility and sustainability make it a vital material in modern engineering and manufacturing.

Aluminium (Al) is a lightweight, silvery-white metal known for its corrosion resistance, ductility, and excellent conductivity. It's widely used in aerospace, construction, transportation, packaging, and electrical industries. Extracted primarily from bauxite ore, aluminium is refined into alumina and then smelted using the energy-intensive Hall-Héroult process. Highly recyclable, aluminium plays a crucial role in sustainable practices and advanced technological applications.
