Aluminium–scandium alloys (AlSc) are aluminum alloys that consist largely of aluminium (Al) and traces of scandium (Sc) as the main alloying elements.In principle, aluminium alloys strengthened with additions of scandium are very similar to traditional nickel-base superalloys in that both are strengthened by coherent, coarsening resistant precipitates with an ordered L1 2 structure.
The alloy Al 20 Li 20 Mg 10 Sc 20 Ti 30 is as strong as titanium, light as aluminium, and hard as some ceramics. [60] Some items of sports equipment, which rely on lightweight high-performance materials, have been made with scandium-aluminium alloys, including baseball bats, [61] tent poles and bicycle frames and components.

Terfenol-D (terbium, dysprosium, and iron), a highly magnetostrictive alloy used in portable speakers such as the SoundBug device; Ferrocerium (cerium, iron) Neodymium magnets, another strong permanent magnet; SmCo ; used for permanent magnets in guitar pickups, headphones, satellite transponders, etc. Scandium hydride
Some items of sports equipment, which rely on high performance materials, have been made with scandium–aluminium alloys, including baseball bats, [56] lacrosse sticks, as well as bicycle [57] frames and components, and tent poles. U.S. gunmaker Smith & Wesson produces revolvers with frames composed of scandium alloy and cylinders of titanium ...
Scandium: from Latin Scandia (Scandinavia). Light aluminium-scandium alloys for aerospace components, additive in metal-halide lamps and mercury-vapor lamps, [11] radioactive tracing agent in oil refineries 22 39 Y Yttrium: after the village of Ytterby, Sweden, where the first rare-earth ore was discovered.

Some manufacturers of bikes make frames out of aluminum alloys containing scandium, usually referred to simply as scandium for marketing purposes although the Sc content is less than 0.5%. Scandium improves the welding characteristics of some aluminum alloys with superior fatigue resistance permitting the use of smaller diameter tubing ...
Scandium hydride, also known as scandium–hydrogen alloy, is an alloy made by combining scandium and hydrogen. Hydrogen acts as a hardening agent, preventing dislocations in the scandium atom crystal lattice from sliding past one another. Varying the amount of hydrogen controls qualities such as the hardness of the resulting scandium hydride ...
