· JVASP-75552· TaAsAu

TaAsAu is a ternary intermetallic compound combining tantalum, arsenic, and gold. This is a specialized research material rather than a commercial alloy, likely investigated for its electronic properties or potential use in semiconductor devices and high-reliability applications where the noble metal (gold) and refractory metal (tantalum) components provide corrosion resistance and thermal stability.

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.
