Aluminum 7075 CNC Machining
7075-T6 aluminum is a high-strength alloy widely used for performance-critical CNC machined components. With excellent strength-to-weight ratio and superior mechanical properties, it is an ideal material choice for aerospace, robotics, and demanding engineering applications.
What is Aluminum 7075?
Aluminum 7075 is a high-strength aluminum alloy primarily containing zinc as the major alloying element. It was developed for applications where higher mechanical strength and fatigue resistance are required compared with standard aluminum alloys.
7075-T6 is the most commonly used temper condition, providing excellent strength while maintaining aluminum’s advantages of lightweight performance and corrosion resistance. It is widely selected for aerospace components, precision fixtures, robotics parts, and other demanding applications.
Compared with 6061 aluminum CNC machining , 7075 aluminum offers significantly higher strength but requires more careful machining strategies due to its hardness and mechanical properties.
At CNCTAL, we manufacture custom 7075 aluminum CNC parts from prototypes to low-volume production, supporting complex geometries, tight tolerances, and professional finishing options.
Why Engineers Choose 7075 Aluminum
- Higher strength-to-weight ratio
- Excellent fatigue resistance for demanding applications
- Suitable for aerospace and performance components
