Rare Earth metal
The main use of Scandium is in the making of aluminum-scandium alloys for aerospace industry components. However, only 0.1% - 0.5% of Scandium is used for this application. Another use of Scandium is in aluminum-scandium alloys for sports equipment, such as bicycle frames, lacrosse sticks, and baseball bats. This is done because the aluminum-scandium alloy allows for high athletic performance. Another application used in Scandium Oxide (Sc2O3) to make high intensity discharge lamps.
