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 steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air ...

US production of primary aluminum peaked in 1980 at 4.64 million metric tons. Since then, US primary aluminum production has fallen by more than half, but secondary production has increased, making up much of the difference. In the 1950s and 1960s, primary production made up about 80% of the aluminum output.
