· JVASP-72123· TiBeNb2

TiBeNb2 is an experimental titanium-beryllium-niobium intermetallic compound combining the lightweight and high-temperature capabilities of titanium with beryllium's stiffness and niobium's refractory properties. This research-phase material targets aerospace and advanced structural applications where ultra-low density combined with thermal stability and strength retention at elevated temperatures offers potential weight and performance advantages over conventional titanium alloys, though processing, cost, and beryllium toxicity management remain significant engineering challenges.

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.
