· JVASP-65059· Ta4BeV

Ta4BeV is a refractory metal intermetallic compound combining tantalum, beryllium, and vanadium. This is an experimental or research-phase material; it belongs to the family of high-melting-point intermetallics explored for extreme-temperature structural applications where conventional superalloys reach their limits. The tantalum-beryllium base suggests potential for aerospace or nuclear thermal environments, though practical engineering adoption remains limited due to the challenging metallurgy of beryllium and the scarcity and cost of tantalum.

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.
