· Co3Ta

Co₃Ta is an intermetallic compound composed of cobalt and tantalum, belonging to the family of refractory metal intermetallics. This material is primarily investigated in research contexts for high-temperature structural applications where the combination of cobalt's ductility and tantalum's high melting point and strength offers potential advantages over conventional superalloys. Co₃Ta and related cobalt–tantalum intermetallics are being developed for aerospace engine components, thermal barrier systems, and other extreme-environment applications where improved high-temperature performance and oxidation resistance are critical, though industrial deployment remains limited compared to established nickel-based superalloys.

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.
