· TiAlAu2

TiAlAu2 is an intermetallic compound combining titanium, aluminum, and gold, belonging to the family of high-density metallic alloys with potential applications in aerospace and electronics. This material is primarily of research interest rather than widespread industrial use, investigated for its unique combination of light alloying elements (Ti, Al) with gold, which may offer advantages in specialized high-performance applications requiring unusual property balances. The inclusion of gold distinguishes it from conventional Ti-Al alloys and suggests potential use in applications where corrosion resistance, thermal stability, or electronic properties are critical alongside mechanical performance.
