The 7020 T7351 aluminum alloy is a high-strength material offering durability and excellent mechanical properties. Belonging to the aluminum-zinc alloy family, this material is especially preferred for aerospace, aviation, and structural applications requiring high performance. The T7351 temper provides high strength, stress resistance, and hardness through specialized heat treatments, while also allowing good machinability. Its high strength-to-weight ratio makes 7020 T7351 ideal for heavy-load components requiring superior durability.

The suitability of the 7020 T7351 aluminum alloy for anodizing is limited. Its high zinc content hinders the formation of an effective oxide layer during anodizing, making protection via this process challenging. Therefore, alternative coating methods are usually preferred to protect the alloy. Regarding weldability, 7020 T7351 requires careful handling during welding. The high zinc content can increase the risk of cracking during welding, so special welding techniques and appropriate filler materials should be used to minimize this risk.

In terms of bending and forming, 7020 T7351 may present challenges due to its high strength. However, with proper processing techniques, bending and forming operations can be successfully performed. Additionally, 7020 T7351 can be safely used in high-vibration environments. Thanks to its high elastic modulus and durability, it is suitable for motor components, chassis, and other vibration-exposed parts.

Regarding corrosion resistance, 7020 T7351 aluminum alloy may have limitations due to its high zinc content. However, with suitable coatings and surface treatments, corrosion resistance can be improved. The advantages of 7020 T7351 include high strength, durability, and light weight, while its disadvantages include limited corrosion resistance and welding difficulties.
