Heat Treatment Condition: T62
The condition is achieved through the following heat treatment processes:
Solution Heat Treatment
The alloy is heated to a certain temperature, held for a period of time to allow the 7075 alloying elements to fully dissolve into the aluminum matrix, and then rapidly cooled (usually by water quenching) to form a supersaturated solid solution.
Artificial Aging
Aging treatment is performed at a lower temperature for a certain period of time, allowing the alloying elements to precipitate and form fine strengthening phases, which significantly improve the material's strength and hardness.
Through this heat treatment process, 7075-T62 aluminum achieves excellent mechanical properties, making it suitable for high-strength applications.

Advantages and Limitations of 7075 T62 Aluminum
Advantages of 7075 T62 Aluminum
Extremely high strength-to-weight ratio
High strength: Compared to other aluminum alloys (such as 6061 or 2024), 7075-T62 has higher tensile and yield strength at the same weight.
High fatigue resistance: It maintains a longer service life under alternating stresses.
Limitations of 7075 T62 Aluminum
Relatively high cost
Poor weldability: Like other heat-treated versions of 7075, the T62 condition has poor weldability, and welding can cause a reduction in material performance. Therefore, welding should be avoided or performed using specific welding techniques.
Brittleness: Although 7075-T62 aluminum alloy has high strength, it may exhibit brittle characteristics under certain stress conditions (such as low temperature or high impact environments).
