TiGa

TiGa is an intermetallic compound combining titanium and gallium, representing an emerging class of lightweight metallic materials. While not yet widely commercialized, TiGa and similar titanium-based intermetallics are of research interest for applications requiring combinations of low density with reasonable stiffness, particularly in aerospace and high-temperature environments where reducing component weight is critical. Engineers would consider this material for advanced aerospace structures, aerospace fasteners, or thermal management components where the material's density-to-stiffness ratio offers potential advantages over conventional titanium alloys, though production maturity and cost remain limiting factors compared to established alternatives.
