Aluminium (Al) is a lightweight, silvery-white metal known for its high strength-to-weight ratio, corrosion resistance, and excellent conductivity. It is the most abundant metal in the Earth's crust, making up about 8% of its composition. Aluminium is widely used across industries due to its versatility, durability, and recyclability.
Atomic number 13, atomic mass 26.98 g/mol, density 2.7 g/cm³, melting point 660.3°C, and boiling point 2470°C. Lightweight yet strong, ductile, malleable, and corrosion-resistant due to its protective oxide layer (Al₂O₃). Highly reactive but protected by its oxide layer; reacts with acids and bases, and is non-magnetic and non-sparking.
