TaAu
metal· JVASP-100638· TaAu
TaAu is a tantalum–gold alloy combining the high density and corrosion resistance of tantalum with the biocompatibility and radiopacity of gold. This material is primarily used in medical device applications where both X-ray visibility and chemical inertness are critical, particularly in implants and diagnostic instruments that must remain stable in the body's corrosive environment. Engineers select TaAu over single-element alternatives when a balance of mechanical robustness, biocompatibility, and radiographic contrast is required—advantages difficult to achieve with tantalum or gold alone.

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.
