7049 Aerospace Aluminum Plate
7049 Aerospace Aluminum Plate is a high-strength aluminum alloy designed for demanding aerospace and defense applications. With a zinc-magnesium-copper composition, it delivers superior tensile strength (~540 MPa), yield strength (~470 MPa), and excellent fatigue crack growth resistance. The alloy is commonly supplied in T7351 and T7451 tempers, ensuring outstanding fracture toughness and dimensional stability after heat treatment.
This aerospace-grade plate is widely used in aircraft wing spars, fuselage frames, landing gear components, and missile systems, where lightweight performance and structural reliability are critical. Its machinability and corrosion resistance make it suitable for both aerospace and high-performance engineering industries.

| 7049 Aluminum Heat Treatment and Tempers: |
7049 aluminum is available in several tempers, each tailored for specific mechanical and corrosion-resistance requirements:
-
T7651 / T7451 – Delivers high strength with excellent stress corrosion resistance, commonly applied in wing spars and fuselage panels.
-
T73 / T7352 – Optimized to resist stress corrosion cracking, making it suitable for landing gear components and missile structures.
-
T6 – Provides maximum strength in the peak-aged condition.
-
T7 – Offers improved corrosion resistance through controlled over-aging.
Heat Treatment Process
7049 aluminum undergoes solution heat treatment at approximately 875°F (468°C), followed by rapid water quenching. Subsequent artificial aging—such as holding at 250°F (121°C) for 24 hours—enhances dimensional stability, fracture toughness, and corrosion resistance depending on the chosen temper.
