The 7010 T7351 aluminum alloy is a high-strength alloy that offers excellent mechanical properties. Belonging to the aluminum-zinc alloy family, this material is particularly preferred in aerospace, aviation, and structural applications requiring high performance. The T7351 temper provides the alloy with high strength and stress resistance through a specialized heat treatment. These properties make the 7010 T7351 alloy ideal for applications bearing heavy loads and requiring high durability.

The 7010 T7351 aluminum alloy has limited suitability for anodizing. Its high zinc content inhibits the formation of an effective oxide layer during the anodizing process, making surface protection through anodizing challenging. Instead, other coating methods are preferred for corrosion protection. Regarding weldability, 7010 T7351 requires careful handling during welding. The high zinc content increases the risk of cracking during welding, which must be minimized using specialized welding techniques and appropriate filler materials.

In terms of bending and forming, the 7010 T7351 aluminum alloy can present challenges due to its high strength. However, with proper processing techniques, bending and forming operations can be successfully performed. Additionally, the 7010 T7351 alloy can be safely used in high-vibration environments. Its high durability and elastic modulus make it suitable for automotive and aerospace components such as engine parts, chassis, and other vibration-prone components.

In terms of corrosion resistance, the 7010 T7351 aluminum alloy has some limitations compared to other aluminum alloys due to its high zinc content. However, corrosion resistance can be enhanced with proper coating and surface treatments. The advantages of 7010 T7351 include high strength, durability, and light weight, while disadvantages include limited corrosion resistance and welding difficulties.
