Wire EDM for Aluminum 6061-T6
Wire EDM of aluminum 6061 is effective for intricate profiles and tight-tolerance features that are difficult to achieve with conventional milling. Aluminum's high conductivity enables fast cutting.
Recommended Machining Parameters
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.02 mm |
| Surface Finish | Ra 0.4-1.0 μm |
| Cutting Speed | Fast — high conductivity |
| Feed Rate | Auto-tuned by EDM controller |
| Tooling Recommendations | Brass wire 0.20-0.25mm for general work. Coated wire for faster cutting. |
Expert Machining Tips
1
Use brass wire for best surface finish
2
Flushing is critical — aluminum produces heavy debris
3
Multiple skim cuts for tight tolerances
4
Slower settings reduce recast layer
