Historia
In 1761, Guyton de Morveau proposed the name alumine for the base in alum, and Antoine Lavoisier, in 1787, thought this to be the oxide of a still undiscovered metal.

Sir Humphry Davy identified the existence of a metal base of alum in 1808.

Hans Christian Ørsted was the first to isolate metallic aluminum in 1825 in impure form.

Friedrich Wöhler is generally credited with having isolated the metal in 1827.

Användningsområden
Aluminum is used in an extensive range of products from drinks cans to window frames and boats to aircraft.

It is used in electrical transmission lines.

It is also used for kitchen utensils, outside building decoration, and in thousands of industrial applications.

When alloyed with small amounts of copper, magnesium, silicon, manganese, or other elements impart a variety of useful properties.
Aluminum is not known to be toxic
