Crude aluminum was isolated in 1825 by Hans Christian Orsted.   Friedrich Wohler produced aluminum powder in 1827 and small globules of the metal in 1845.  The new metal was introduced to the public in 1855 at the Paris exposition. Uses - aluminum cans and foil, reflectors, airplanes, kitchen utensils, building material
