· TiAu2

TiAu2 is an intermetallic compound combining titanium and gold in a 1:2 atomic ratio, belonging to the family of titanium-gold intermetallics. This material is primarily of research interest for applications requiring the combined benefits of titanium's structural properties and gold's chemical inertness and biocompatibility. It sees limited but specialized use in biomedical devices and high-reliability electronics where corrosion resistance, biocompatibility, and specific stiffness are critical; engineers might select it over conventional titanium alloys when gold's non-reactivity is essential or over pure gold when higher structural rigidity is needed.
