![]() In 1954, aluminium became the most produced non-ferrous metal, surpassing copper. In World Wars I and II, aluminium was a crucial strategic resource for aviation. Aluminium became much more available to the public with the Hall–Héroult process developed independently by French engineer Paul Héroult and American engineer Charles Martin Hall in 1886, and the mass production of aluminium led to its extensive use in industry and everyday life. The first industrial production of aluminium was initiated by French chemist Henri Étienne Sainte-Claire Deville in 1856. The discovery of aluminium was announced in 1825 by Danish physicist Hans Christian Ørsted. The strong affinity towards oxygen leads to aluminium's common association with oxygen in nature in the form of oxides for this reason, aluminium is found on Earth primarily in rocks in the crust, where it is the third most abundant element after oxygen and silicon, rather than in the mantle, and virtually never as the free metal. The aluminium cation Al 3+ is small and highly charged as such, it is polarizing, and bonds aluminium forms tend towards covalency. The radioactivity of 26Al is used in radiodating.Ĭhemically, aluminium is a weak metal in the boron group it forms compounds primarily in the +3 oxidation state, as is common for the group. It has one stable isotope, 27Al this isotope is very common, making aluminium the twelfth most common element in the Universe. ![]() Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. In British literature the element's name is spelled alumin ium and the extra syllable pronounced: al - min - i - um.Īluminium ( aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13.

In those cases, the origin of the symbol used is given. ![]() A very few elements have symbols which appear to have no relationship with their names. In some cases, the first letter together with some other letter from their name was used, particularly when their first two letters had already been allocated to another element. ![]() Most chemical elements are represented symbolically by two letters, generally the first two in their name.
