Ta2Au
metal· JVASP-146662· Ta2Au
Ta₂Au is an intermetallic compound formed from tantalum and gold, belonging to the binary metal alloy family. This material combines the high-temperature stability and corrosion resistance of tantalum with gold's chemical inertness and wear resistance, making it of interest for specialized high-performance applications. Research into Ta–Au intermetallics has focused on jewelry, thin-film electronics, and corrosion-critical environments where both mechanical reliability and surface durability are essential.

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.
