The 7049 T7351 aluminum alloy is known for its high strength, durability, and excellent mechanical properties. As part of the aluminum-zinc alloy family, it is primarily used in aerospace, space, and high-performance structural applications. The T7351 temper, achieved through specific heat treatments, provides the alloy with high durability and hardness while maintaining machinability. This alloy is not suitable for anodizing due to its high zinc content, which can complicate the anodizing process. In terms of weldability, it requires careful handling as there is an increased risk of cracking during welding. The 7049 T7351 alloy is suitable for bending and forming, though careful processing is needed due to its high strength. It is also suitable for use in high-vibration environments, as its high elastic modulus and durability make it ideal for components such as engine parts and chassis. Corrosion resistance is limited due to its high zinc content, but this can be improved with proper coating and surface treatments. The advantages of the 7049 T7351 alloy include high strength, durability, and lightweight properties, while its disadvantages include limited corrosion resistance and challenges in welding.
