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.
