· JVASP-90009· TaFeB

TaFeB is an intermetallic compound composed of tantalum, iron, and boron, belonging to the refractory metal alloy family. This material is primarily of research interest for high-temperature and wear-resistant applications, leveraging tantalum's exceptional melting point and chemical inertness combined with iron and boron's strengthening effects. TaFeB represents an emerging system for advanced aerospace, tooling, and thermal protection environments where conventional superalloys reach their limits.

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.
