TaCoAs
metal· JVASP-144600· TaCoAs
TaCoAs is a ternary intermetallic compound combining tantalum, cobalt, and arsenic, representing a research-phase material in the high-density metal alloy family. While not yet widely deployed in production, such tantalum-based intermetallics are investigated for applications requiring extreme density, high-temperature stability, and corrosion resistance—particularly in aerospace, nuclear, and advanced materials research where conventional superalloys reach performance 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.
