Characteristic

Titanium aluminide, commonly gamma titanium, is an intermetallic chemical compound. It is lightweight and resistant to oxidation and heat, however it suffers from low ductility. The density of γ-TiAl is about 4.0 g/cm³. 

Application

Titanium aluminide is used in aircraft turbine engines, exhaust valves and turbochargers for passenger vehicle engines, intermediate process for some mill products.
