· JVASP-54577· TiInAu2

TiInAu2 is an intermetallic compound combining titanium, indium, and gold in a fixed stoichiometric ratio, representing a specialized alloy in the class of precious-metal intermetallics. This material is primarily of research and experimental interest rather than established industrial production, with potential applications in high-reliability electronic contacts, dental/biomedical devices, and specialized aerospace components where the combination of titanium's biocompatibility and strength with gold's corrosion resistance offers unique property synergies. Engineers would consider this material when conventional alloys cannot meet simultaneous demands for oxidation resistance, thermal stability, and biocompatibility, though its cost, limited supply chain maturity, and complex processing requirements restrict current adoption to specialized niche applications.

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.
