· JVASP-151733· TaCoSi

TaCoSi is a ternary intermetallic compound combining tantalum, cobalt, and silicon—a research-stage material belonging to the family of refractory metal silicides and intermetallics. These materials are explored for extreme-environment applications where conventional superalloys reach their limits, leveraging tantalum's high melting point and refractory character alongside cobalt's strength and silicon's lightweight contribution. TaCoSi and related compositions remain primarily in academic and exploratory development rather than high-volume production, with potential applications in aerospace propulsion, high-temperature structural components, and wear-resistant coatings where thermal stability and oxidation resistance justify the material's density and cost.

Export Control

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.
