Titanium aluminide: TiAl

Ti-48Al-2Cr-2Nb
TiAl is a new class of aerospace alloys that offers an excellent strength-to-weight ratio as well as high chemical and thermal stability. Gamma titanium aluminide alloy has excellent mechanical properties as well as oxidation and corrosion resistance at elevated temperatures (over 600 degrees Celsius). TiAl is the latest class of materials competing with Nickel superalloys for the fabrication of aircraft engine parts such as low-pressure turbine (LPT) blades.

Powder chemical composition may comply with standards: AMS7023 or equivalent standard

    TiAl powders are created at AP&C using its proprietary plasma atomization process. The plasma atomization process has a high degree of controllability and uses plasma torches to transform the raw material or liquid metal stream into a powder

      After atomization, the powder is sieved according to customer specifications.

      Titanium Aluminide (TiAl) is one of the most challenging metal alloy powders within additive manufacturing, yet increasingly customers are realizing its potential for high-end applications where performance is key.
