About Aluminium

This chemical element has got its name from the Latin expression meaning bitter salt. It is the most abundant metal on our planet, valued highly for its high conductivity. Aluminium has excellent ratio of being strong and light, thus it is extensively used in aviation for producing planes and other aircrafts. Aluminium is quite reactive but has high resistance to corrosion by creating a layer of it oxide on the surface. Despite being the most abundant metal, aluminium is rare to be found in its pure form, and usually is produced from bauxites, cryolites, and other minerals. In old times, aluminium used to be considered a precious metal like gold, but for the last century its production technology became was cheaper and common. Industrial uses of this metal are really numerous, and those include automobile, construction, kitchenware and household, food, cosmetics, and other branches.
