7. Key Features & Benefits

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.
