Pros and Cons of 6061-T6 Aluminum for CNC Machining
Advantages
- Excellent machinability
Cuts cleanly with carbide tools and supports high-speed milling and turning. - Strong and lightweight
Ideal for structural components that must remain rigid without adding weight. - Corrosion resistant
Works well for outdoor or marine environments, especially when anodized. - Cost-effective
Less expensive than aerospace-grade materials like 7075-T6. - Good weldability
Supports post-machining welding or structural assembly. - Stable T6 temper
Heat treatment ensures predictable hardness and dimensional consistency.
Disadvantages
- Not as strong as 7075
For extreme load-bearing applications, 7075 may be a better choice. - Moderate fatigue resistance
Not ideal for highly repetitive stress environments. - Susceptible to slight burrs
Requires optimized toolpaths and deburring for clean edges. - Can deform if thin-walled
Thin areas need careful fixturing to prevent vibration or warping.
These pros and cons help customers decide whether 6061-T6 is suitable for their CNC aluminum parts.
