This heat treatment capability enables aluminum profiles to meet the stringent performance requirements during the machining process, suitable for the aerospace field's high standards for material strength and reliability.

Surface treatment: The 7049 aluminum alloy is also easy to undergo surface treatments, such as anodizing or coating, to enhance its corrosion resistance and wear resistance. This treatment not only improves the durability of the material but also enhances its appearance, meeting the dual demands of aesthetics and durability in aircraft.

3. Good Fatigue Performance

Dynamic load-bearing capacity: The 7049 aluminum alloy exhibits excellent performance when subjected to repeated loads (such as aerodynamic loads encountered during flight, impacts from landing gear, etc.). This is because the microscopic structure of the material can effectively disperse stress, reducing the probability of fatigue damage.

Durability: Due to its good fatigue performance, 7049 aluminum profiles can maintain high strength over long-term use, reducing the risk of failure due to material fatigue. This durability is crucial in structural components of aircraft, especially in critical areas that require high safety standards.

Reliability: The fatigue performance of 7049 aluminum alloy allows it to maintain good operational status even under extreme conditions, enhancing the overall safety and reliability of the aircraft. This makes the 7049 aluminum profile more widely applicable in the aerospace field, particularly in critical structural components.
