7075-T73510 aluminum alloy belongs to the 7xxx series aluminum alloys and is a zinc (Zn)-based high-strength alloy, representing an overaged temper condition. Compared to T6, the T73510 temper provides lower strength but significantly improved resistance to stress corrosion cracking (SCC). This temper is preferred in applications where reliability and long service life are critical.

In terms of strength and mechanical properties, 7075-T73510 has lower yield and tensile strength than T6 and T6510 tempers, but it still offers significantly higher strength than 6xxx series alloys (such as 6061-T6). The overaging process alters the precipitate structure, reducing strength slightly while improving material stability.

In terms of corrosion resistance, this temper shows its main advantage. 7075-T73510 exhibits high resistance to stress corrosion cracking, making it much safer than the T6 condition. Compared to 2024 alloy, it provides better SCC resistance, although it does not reach the general corrosion resistance level of 5xxx series alloys (such as 5083). Surface protection such as anodizing or coating is commonly applied.

Regarding machinability, bending, and weldability, 7075-T73510 offers good machinability but lower formability compared to the O temper. Care must be taken during bending operations, as the hardened structure increases the risk of cracking. Weldability is generally poor, and in this respect, 6061 alloy is much more advantageous. Therefore, mechanical fastening methods are usually preferred.

In terms of vibration response and applications, due to its high specific strength and improved corrosion resistance, 7075-T73510 is widely used in aerospace, defense industry, tooling, high-performance machinery parts, and critical load-bearing structures. This temper is especially preferred for thick sections and provides reliable performance under long-term loading. While 7075-T6 is used where maximum strength is required, T73510 is preferred in applications where safety and durability are prioritized.
