· JVASP-92775· LuFe2B2

LuFe2B2 is an intermetallic compound combining lutetium, iron, and boron—a rare-earth iron boride belonging to the family of hard, refractory materials. This is primarily a research material studied for its potential in high-hardness and high-temperature applications, rather than a widely commercialized engineering alloy. The lutetium-iron-boron system is of interest for specialized applications requiring extreme hardness, thermal stability, or magnetic properties, though industrial adoption remains limited.

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.
