· TiAu

TiAu is an intermetallic compound combining titanium and gold, belonging to the family of binary metallic systems. This material exhibits characteristics intermediate between its constituent metals, offering potential for specialized applications where the properties of both titanium (strength, low density, biocompatibility) and gold (corrosion resistance, electrical conductivity) are advantageous. TiAu remains primarily a research and development material rather than a commodity engineering alloy, with investigation focused on biomedical implants, electronics interconnects, and corrosion-resistant coatings where the combination of biocompatibility, chemical inertness, and mechanical stability is sought.

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.
