Aluminum

The most abundant metal in the crust of the Earth. Because it is not very dense and is resistant to corrosion, it has a wide variety of commercial uses, notably in transportation, packaging, and construction. It is also used in home appliances. Aluminum is also spelled aluminium, especially in countries where British English predominates.
