Aluminium single crystal 13Al26.9815
Discovered in 1825 by Oersted at Copenhagen, Denmark.
[Latin: alumen = alum]
French: aluminium
German: aluminium
Italian: alluminio
Spanish: aluminio
Description: Pure aluminium is soft and malleable, but can be toughened by alloying with small amounts of other metals like copper and magnesium. Aluminium objects are protected from reacting with air and water by an oxide film which forms rapidly on the surface. Aluminium is soluble in concentrated hydrochloric acid and in sodium hydroxide solution. The metal and its alloys have hundreds of uses in the vehicle, aircraft, and construction industries. It is used to make cans kegs, wrapping foil, household utensils, etc.
