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

O alumínio é um elemento químico de símbolo Al e número atómico 13 (treze prótons e treze elétrons). O alumínio tem uma densidade mais baixa do que outros metais comuns; aproximadamente um terço do aço.

El aluminio es un elemento metálico representado en la tabla periódica con el símbolo ‘Al’ y el tercer elemento más común de la corteza de nuestro planeta: un 8 % de la corteza terrestre contiene aluminio en diversos compuestos.

Aluminum alloys are second only to steels in use as structural metals. Aluminum has a density of only 2.7 g/cm3, approximately one-third as much as steel (7.83 g/cm3). One cubic foot of steel weighs about 490 lb; a cubic foot of aluminum, only about 170 lb.

Es un elemento químico metálico de la tabla periódica, su estado natural se consigue en muchos silicatos como micas, feldespatos y plagioclasas. Se extrae de la bauxita por transformación primero en alúmina y luego por medio de electrólisis en aluminio metálico. El aluminio símbolo que se encuentra en la tabla periódica es 'Al'.
