· JVASP-128723· Ti2Au

Ti2Au is an intermetallic compound composed of titanium and gold, forming part of the Ti–Au binary phase diagram. This material is primarily of research and specialized industrial interest rather than a commodity engineering material, with applications driven by the unique combination of titanium's strength-to-weight ratio and gold's biocompatibility, corrosion resistance, and radiopacity. It has potential use in high-performance biomedical devices, aerospace components requiring gold coating adhesion, and dental/orthopedic applications where both mechanical strength and biological tolerance are critical; however, its high material cost and complex processing limit broader adoption compared to conventional titanium alloys or gold coatings.

Export Control

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.
