· JVASP-39269· LuAlB4

LuAlB4 is an intermetallic compound combining lutetium, aluminum, and boron, belonging to the rare-earth metal boride family. This material is primarily of research and development interest rather than established industrial production, with potential applications in high-temperature structural materials and advanced ceramics where the combination of rare-earth strengthening and boride hardness could provide enhanced performance. Engineers would consider this material class for extreme environment applications where conventional superalloys or ceramics reach performance limits, though maturity, scalability, and cost currently limit adoption.

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.
