7075-T73511 aluminum alloy belongs to the high-strength 7xxx series and represents a temper specifically developed to improve resistance to stress corrosion cracking (SCC). The T73511 temper involves solution heat treatment, controlled over-aging, and stress-relieving processes. This combination results in slightly lower strength than T6, but significantly improved corrosion resistance and dimensional stability.

In terms of corrosion resistance, 7075-T73511 offers excellent resistance to stress corrosion cracking. While 7075-T6 is susceptible to SCC despite its high strength, T73 variants significantly reduce this issue. The 2024 alloy is also prone to corrosion and often requires cladding, whereas 5083 provides superior natural corrosion resistance. However, 7075-T73511 offers a balanced solution where high strength is required.

Regarding strength and mechanical properties, 7075-T73511 provides high tensile and yield strength, although somewhat lower than T6. This is compensated by improved toughness and resistance to crack propagation. Compared to 6061-T6, it offers significantly higher strength. Compared to 2024-T351, it generally provides higher strength and better SCC resistance, making it suitable for critical structural applications.

In terms of machinability, bending, and weldability, 7075-T73511 offers good machinability, but bending is limited due to high strength and requires caution. The stress-relieved structure of T73511 provides better dimensional control than T6. Weldability is generally poor; in this regard, 6061 performs much better. Anodizing is possible, although copper content may affect surface appearance.

Regarding vibration behavior and applications, 7075-T73511 is widely used in aerospace, defense, and tooling industries due to its high specific strength, good fatigue resistance, and improved corrosion performance. It is commonly used in aircraft structural components, mold plates, load-bearing parts, and systems operating under high stress. While 2024 stands out for fatigue performance, 7075-T73511 offers a superior combination of strength and environmental resistance.
