Aluminium was discovered by Hans Oersted in Copenhagen, Denmark in 1825.
Aluminium is a silvery white reactive metal which is usually covered by a tenacious oxide coating. This renders it inert to acids, but it is attacked by alkalies. It is the most common metallic element in the earth's crust (82000 ppm) and is extracted from the hydrated oxide, Bauxite, by electrolysis of the oxide dissolved in molten sodium hexafluoroaluminate (cryolite). The metal has good thermal properties and is malleable and ductile. Aluminium and its alloys are widely used for various applications including aircraft assemblies and engine parts.
Microleaf - An extremely thin sheet of metal mounted on a removable support. Microleaf is not available for metals which are too brittle to be free standing. Microleaf is mounted on a specially treated support which allows separation of the metal film from the support. Full instructions on the method of removal are issued with each Microleaf supplied.
