Product Description

 

Scandium Metal is applied in optical coating, catalyst, electronic ceramics and laser industry. The main application of Scandium by weight is in Aluminium-Scandium alloys for minor aerospace industry components. Some items of sports equipment, which rely on high performance materials, have been made with Scandium-Aluminium alloys. Employed in solid state synthesis of unusual clusters, Sc19Br28Z4, (Z=Mn, Fe, Ru or Os). These clusters are of interest for their structure and magnetic properties. It is also applied to make super alloy.

Application:

Rare earth (RE) elements have also been successfully alloyed with Mg. Addition of rare earth (RE) elements can refine grains and weaken anisotropy to improve the ductility of the Mg alloys. In addition, RE elements give rise to a dispersion of thermally stable precipitates with high melting point (above 620 °C), an improvement over precipitates of the Mg-Zn system which melt at approximately 340°C and thus have poor thermal stability and exhibit tendency for hot tearing.
