During the Cold War, the Russians were the first to use Scandium with Aluminum alloys, and it was used for military endeavors such as the fins on ballistic missiles (for blasting through polar ice) and MiG fighter jets. Scandium is used as a grain refining additive for Aluminum. It enhances malleability, strength, integrity of welds, resistance to recrystallization and fatigue life of the aluminum. For bicycling applications a thinner walled and lighter tubing can be used. Most of the Scandium used in the US goes into high-intensity lights. Scandium is quite expensive, costing in the neighborhood of $120 per gram ($55,000 per pound).

My test stead Ibis Mojo takes a 31.6 seatpost, and it is accessorized in Red, so I had an easy choice to test, Red!
