| Feature | Benefit |
| ★ Outstanding High-Temperature Strength | Maintains high tensile and yield strength up to 700°C (1292°F) after age hardening, ideal for aerospace engine and gas turbine sheet metal components. |
| ★ Excellent Creep & Rupture Resistance | Suitable for long-term service under load at elevated temperatures, ensuring dimensional stability in critical sheet components. |
| ★ Superior Oxidation Resistance | Withstands continuous service in oxidizing environments up to 980°C (1800°F), suitable for exhaust systems, combustion liners, and heat shields. |
| ★ Good Corrosion Resistance | Resists a wide range of acidic and caustic media, plus stress corrosion cracking in chloride-containing environments. |
| ★ Precipitation Hardening Capability | Achieves superior strength through γ'' phase precipitation (Al/Ti), enabling tailored mechanical properties for specific applications. |
| ★ Excellent Formability (Solution-Annealed) | Readily fabricated by cold working, stamping, and deep drawing in the solution-annealed condition before precipitation hardening. |
