Aluminum was discovered by Hans Oersted in Copenhagen, Denmark in 1825. Aluminum 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. Aluminum and its alloys are widely used for various applications including aircraft assemblies and engine parts.

Aluminium precision density-standard cube 1cm3 NEW!

Using finest materials, each density cube was lapped to 10x10x10mm by a mechanical engineering company with an accuracy of 0.01 millimeter. Each one separately ground and polished it represents the theoretical density of the respective element by its weight. The weight is not affected by the laser inscription. Information such as element symbol, name and density is durable burned at the surface. Each element even shows its specific characteristis in colour and reaction with the laser. Altogether 25 elements are planned in a complete set in a wooden case.
