· JVASP-102990· TiAu3

TiAu3 is an intermetallic compound combining titanium and gold in a 1:3 atomic ratio, forming a brittle metallic phase with high density and significant stiffness. This material is primarily of research and specialized interest rather than widespread industrial use; it belongs to the titanium-gold intermetallic family explored for potential applications requiring exceptional hardness and chemical inertness, though its brittleness and high cost limit adoption compared to conventional titanium alloys or gold-based systems.

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.
