Aluminium - Wikipedia

Aluminium (aluminum in American and Canadian English) is a chemical element with the syol Al and atomic nuer 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel.It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually reseles silver, both in its color and
