Aluminium - Wikipedia

Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13 Aluminium has a density lower than those of other common metals, at approximately one third that of steelAluminium has a great affinity towards oxygen, thanks to which it forms a protective layer of oxide on the surface Aluminium visually resembles silver, both in color and in ,

Aluminum is far more electronegative than iron, with a value of 15 versus 18, and is well-known to have a much higher enthalpy of combustion (both on a molar and on a per-mass scale) The mean oxide film thicknesses of iron and aluminum are also supposedly comparable, on the order of 3 nanometers, so unless carbon steel acts differently, it ,
