Oxygen Free Copper EDM Electrodes & Drills
Oxygen Free Copper: Superior Conductivity for Precision EDM
Oxygen-Free Copper (OFHC/OFCu) electrodes, with their 99.97% copper purity, provide unmatched electrical conductivity compared to standard 99% pure copper electrodes. This superior purity minimizes material resistance, enhancing machining precision, durability, and efficiency.
Engineered for high-precision machining, OFC electrodes are a game-changer for applications requiring fast burn rates, reduced heat distortion, and consistent performance.
Copper (C1220T) vs. Oxygen Free Copper (C10200T)
| Property | Standard Copper (C1220T) | Oxygen Free Copper (C10200T) |
|---|---|---|
| Purity | 99% | 99.97% |
| Electrical Conductivity | Lower, with more resistance | High, reduces energy loss |
| Thermal Stability | Prone to heat distortion | Minimized thermal expansion |
| Durability | Moderate | Enhanced longevity |
| Burn Rate | Slower | Faster |
The higher conductivity and purity of oxygen-free copper electrodes make them indispensable for applications requiring efficiency, durability, and precision.
When to Choose Oxygen Free Copper Electrodes
When It’s Ideal:
- High-volume machining operations requiring consistent performance.
- Applications with tight tolerances and detailed precision, such as aerospace and medical devices.
- When minimizing thermal distortion and maximizing electrode life is critical.
When It’s Not Necessary:
- When working on soft materials that do not require advanced flushing or cooling.
- When extreme toughness is required—tungsten carbide may be a better choice.For soft materials where copper electrodes could achieve the same results at a lower cost.
Case Study: Aerospace Application
In January 2016, an aerospace company sought to enhance production efficiency while meeting strict specifications for drilling rocket motor components. By switching from standard copper to oxygen-free copper electrodes, the company:
- Reduced electrode changeovers, improving cycle time efficiency.
- Achieved faster burn rates without altering machine settings or part specifications.
- Maintained compliance with contractual quality requirements while enhancing productivity.
This transition highlighted the unmatched advantages of oxygen-free copper electrodes in precision-focused industries.
