What is 7075 Aluminum?

7075 Aluminum

7075 aluminum is a high-strength aluminum alloy known for its excellent strength-to-weight ratio, fatigue resistance, and superior mechanical properties. It is widely used in aerospace, automotive lightweight applications, and high-performance mechanical components where high strength and reliability are required.

Compared with the commonly used 6061 aluminum alloy, 7075 aluminum offers higher strength and hardness, making it suitable for precision components used in high-load and high-stress environments. However, due to its higher hardness, machining 7075 requires advanced equipment, proper tooling selection, and precise process control to achieve high-quality results.

7075 Aluminum Grades and Tempers: 7075 aluminum is mainly classified by its heat treatment conditions. The most commonly used tempers include:

7075-T6: 7075-T6 is solution heat-treated and artificially aged to achieve high strength and hardness. It is one of the most widely used tempers for 7075 aluminum applications.

Key Features:

• High strength and hardness
• Excellent fatigue performance
• Suitable for high-load components

• Aerospace structural components
• Precision mechanical parts
• High-performance equipment components

7075-T651
7075-T651 is based on the T6 temper with additional stress-relief stretching, which helps reduce internal stresses and improve dimensional stability during machining.

Key Features:

• Improved machining stability
• Reduced risk of deformation
• Suitable for large precision components

• Aerospace components
• High-precision CNC machined parts
• Industrial equipment structures
