Aluminium is a silvery-white, soft, ductile and non-magnetic metal. It is the third most abundant element after oxygen and silicon, and the most abundant metal in the Earth’s crust. Aluminium is remarkable for its extremely low density, and its ability to resist corrosion through the phenomenon of passivation by oxidation, whereby it forms a thin, protective layer on its surface.
The lightweight, 100 percent-recyclable metal, and its alloys have become the backbone of urban infrastructure and multiple industries today. Aluminium is used in the packaging, aerospace, automotive and construction industries, and in transportation, energy, and defence applications.
