TiAlAu
metal· TiAlAu
TiAlAu is a ternary intermetallic alloy combining titanium, aluminum, and gold, representing an experimental composition in the titanium-aluminum family of materials. This material is primarily of research interest, as it combines the lightweight and high-strength characteristics of titanium-aluminum intermetallics with gold's exceptional corrosion resistance and biocompatibility—a combination not typically found in commercial alloys. The inclusion of gold makes TiAlAu a candidate for specialized applications where corrosion immunity and biological tolerance are critical alongside mechanical performance, though its use remains limited to investigation in academic and advanced materials development settings.

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.
