Scandium Metal is applied in various superalloys which show excellent metallic performance with their light gravaty. The main application of Scandium by weight is in Scandium-Aluminium alloys for minor aerospace industry components. They were used in the Russian military aircraft, specifically the MiG-21 and MiG-29. Some items of sports equipment, which rely on high performance materials, have been made with Scandium-Aluminium alloys. Employed in solid state synthesis of unusual clusters, Sc19Br28Z4, (Z=Mn, Fe, Ru or Os). These clusters are of interest for their structure and magnetic properties.
