Sc(MnAl2)4
metal· Sc(MnAl2)4
Sc(MnAl2)4 is an intermetallic compound combining scandium, manganese, and aluminum in a defined crystallographic structure. This material belongs to the family of lightweight refractory intermetallics and is primarily of research interest rather than established production use, explored for applications requiring high stiffness-to-weight ratios and elevated-temperature stability. The inclusion of scandium—a rare earth element with strong strengthening effects—makes this compound notable for potential aerospace and high-performance structural applications where conventional aluminum alloys or titanium reach thermal or weight limitations.
