KCNC Ti Pro Lite Scandium Road Cyclocross MTB Bicycle Bike Seatpost What is SCANDIUM? Scandium is a chemical element with symbol Sc and atomic number 21. Scandium is present in most of the deposits of rare-earth and uranium compounds, but it is extracted from these ores in only a few mines worldwide. Because of its rarity, scandium is among the most expensive elements. Due to the low availability and the difficulties in the preparation of metallic scandium, which was first done in 1937, applications for scandium were not developed until the 1970s. Scandium has until now only been a niche metal with demand in high end products such as the aerospace industry and sports equipment (bicycle frames, fishing rods, golf iron shafts, tennis rackets and baseball bats). Scandium, when added to aluminum, creates a strong lightweight alloy with excellent resistance to corrosion and good weldability. Aluminum-scandium alloy can be 10-100% stronger than conventional aluminum alloys and has been also used in Russian MIG fighter planes. Some items of sports equipment, which rely on high-performance materials, have been made with scandium-aluminium alloys, including baseball bats and bicycle frames and components. is one of few brands which uses scandium on their bike parts.
