Elroy as usual you are getting in a chicken and egg argument without any practical or useful purpose, just to prove your "smartness". I do know of those deposits, (they are mentioned in Wikipedia) nothing new there, my proposal is to extract from certain mining tailings that is all. Use of scandium in super alloys seem to be relatively new. The properties and application of scandium-reinforced aluminum Scandium-reinforced aluminum alloys represent a new generation of high-performance alloys that display numerous advantages over high-strength aluminum alloys. Scandium-reinforced alloys are much stronger than other high-strength alloys, exhibit significant grain refinement, strengthen welds, and eliminate hot cracking in welds. These alloys also exhibit a good resistance to corrosion as shown by recent studies. A review of their mechanical, microstructural, and corrosion characteristics shows that scandium-reinforced alloys can be usefully employed in aerospace, sports, transportation, and process industries. The information on scandium-reinforced alloys is scanty; very little has been published on the mechanical, microstructural, and corrosion behavior of these alloys . link.springer.com Parts of the MiG-29 are made from Al-Sc alloy.
