· JVASP-129401· ThNb

ThNb is a thorium-niobium intermetallic compound belonging to the refractory metal alloy family, designed for extreme-temperature and high-strength applications. While primarily investigated in research and development contexts rather than widespread commercial production, this material class is explored for aerospace propulsion systems, nuclear reactor components, and other demanding environments where conventional superalloys reach their thermal limits. ThNb's potential lies in leveraging thorium's nuclear properties and niobium's refractory characteristics to achieve superior high-temperature strength and oxidation resistance compared to nickel- or cobalt-based alternatives.

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.
