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.
The assertion that "Aluminium is the element, Aluminum is the alloy" contradicts established scientific consensus. According to the IUPAC (International Union of Pure and Applied Chemistry), the correct term for the element with atomic number 13 is "Aluminium". In American English, the term "Aluminum" refers to the same element, not an alloy.
Alum in the form of potassium aluminium sulphate or ammonium aluminium sulfate in a concentrated bath of hot water is regularly used by jewelers and machinists to dissolve hardened steel drill bits that have broken off in items made of aluminum, copper, brass, gold (any karat), silver (both sterling and fine) and stainless steel. This is ...
When editors themselves translate text into English, care must always be taken to include the original text, in italics (except for non-Latin-based writing systems, and best done with the {} template which both italicizes as appropriate and provides language metadata); and to use actual and (if at all possible) common English words in the ...
The introduction of these methods for the mass production of aluminium led to extensive use of the light, corrosion-resistant metal in industry and everyday life. Aluminium began to be used in engineering and construction. In World Wars I and II, aluminium was a crucial strategic resource for aviation.

But why not resolve this dispute by calling aluminium aluminum aluminium aluminum the thirteenth element on the periodic table "niluntrium" (derived from the IUPAC systematic element names. And it would have the symbol "Nut", which is pretty much how I'd sum up this dumb debate. -- 116.14.27.127 ( talk ) 14:32, 3 June 2009 (UTC)
