AEM can provide various scandium products including:
Scandium was discovered in 1879 by L.F. Nilson and takes its name from the 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, thertveitite, wolframite and euxenite (a niobate, tantalate and titanate of several rare elements in which scandium was originally discovered). It is a metal which tarnishes in air (shows a pink colouration), burns easily and reacts with water to produce hydrogen gas. Scandium turnings ignite in 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 common 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, giving it uses in aerospace and other manufacturing, such as racing bicycles. Another application is scandium-aluminum alloys can be used in some sports equipment, including baseball bats, lacrosse sticks, as well as bicycle frames and related components. Packaging of our scandium elements products are clearly tagged and labeled externally to ensure efficient identification and quality control.
Applications for scandium have not yet been fully investigated and its use is limited primarily to research.
