Aluminium (the Commonwealth and preferred IUPAC name) or aluminum (North American English) is a chemical element; it has symbol Al and atomic number 13. It has a density lower than other common metals, about one-third that of steel. Aluminium has a great affinity toward oxygen, forming a protective layer of oxide on the surface when exposed to air. It visually resembles silver, both in its ...

Aluminium, with the symbol Al, is a silvery-white, lightweight, and ductile metal. It's renowned for its low density and corrosion resistance, making it one of the most widely used metals in the world. As a metal, it's a good conductor of electricity and heat, and it's malleable, allowing it to be rolled into thin sheets or pulled into wires.
Applications of Aluminium Aluminium and its alloys are used widely in aerospace, automotive, architectural, lithographic, packaging, electrical and electronic applications. It is the prime material of construction for the aircraft industry throughout most of its history. About 70% of commercial civil aircraft airframes are made from aluminium alloys, and without aluminium civil aviation would ...
