· JVASP-8023· LuAl3

LuAl3 is an intermetallic compound composed of lutetium and aluminum, belonging to the rare-earth–aluminum intermetallic family. This material is primarily of research interest rather than established production use, studied for its potential in high-temperature applications and advanced functional materials where the unique combination of rare-earth and lightweight aluminum provides theoretical advantages. Engineers considering LuAl3 would typically be working in aerospace, materials research, or advanced alloy development contexts where novel intermetallic phases are evaluated for specific property combinations not available in conventional alloys.
