AEM provides various Scandium products, including:
Scandium was discovered in 1879 by L.F. Nilson. Its name is taken from a Latin word "Scandia", meaning "Scandinavia".
Scandium (Sc) is a silvery-white metallic transition metal, often classified as a rare earth element (REE), together with yttrium (Y) and the 15 lanthanides (La). It has been identified in several minerals, including cerite, orthite, thortveitite, wolframite, and euxenite (a niobate, tantalate, and titanate of several rare elements in which scandium was originally discovered). It is a metal that tarnishes in the air (shows a pink coloration), burns quickly, and reacts with water to produce hydrogen gas. Scandium turnings ignite in the air with a brilliant yellow flame to form scandium (iii) oxide. The main application of scandium elements is in aluminum-scandium alloys (Sc-Al alloys) for minor aerospace industry components. The standard content is 2% scandium. The addition of scandium to aluminum limits an excessive grain growth that occurs in the heat-affected zone of welded aluminum components. It is a light material with a higher melting point than aluminum. It is used in aerospace and other production, such as racing bicycles. Another application is that scandium-aluminum alloys can be used in some sports equipment, including baseball bats, lacrosse sticks, and bicycle frames, and related components. Packaging our scandium elements products is carefully tagged and labeled externally to ensure efficient identification and quality control.
Applications for scandium have not yet been thoroughly investigated, and its use is limited primarily to research.
