· JVASP-129363· LuNb

LuNb is an intermetallic compound combining lutetium and niobium, belonging to the refractory metal intermetallic family. This material is primarily investigated in research and advanced aerospace contexts for high-temperature structural applications, where its combination of a refractory base metal (niobium) with lutetium's density and potential for phase stability offers promise for extreme-environment performance. While not yet widely deployed in mainstream engineering, LuNb represents the class of rare-earth–transition-metal intermetal­lics being developed for next-generation turbine engines, hypersonic vehicles, and other applications demanding exceptional thermal and mechanical stability beyond conventional superalloys.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
