· JVASP-71272· TaBeW

TaBeW is a refractory metal alloy combining tantalum, beryllium, and tungsten, designed for extreme-temperature and high-strength applications where conventional superalloys reach their limits. This material family is primarily investigated for aerospace propulsion systems, advanced nuclear reactor components, and specialized defense applications where resistance to thermal cycling, oxidation, and mechanical stress at elevated temperatures is critical. TaBeW represents a research-focused composition aimed at surpassing the performance envelope of nickel-based superalloys and traditional refractory metals, though industrial adoption remains limited compared to established alternatives like tungsten-rhenium or tantalum alloys.

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.
