The Science of 99.97% Purity: Technical Roadmap

Oxygen Free Copper (OFC), specifically C10100 and C10200 grades, represents the pinnacle of copper metallurgy. Unlike Electrolytic Tough Pitch (ETP) copper, OFC is produced through a vacuum induction melting process that reduces oxygen levels to below 10ppm. This 99.97% purity ensures zero hydrogen embrittlement and unparalleled thermal conductivity.

🔬

Microstructural Integrity

High purity prevents the formation of cuprous oxide at grain boundaries. This results in superior ductility and impact strength, making it ideal for deep drawing and complex stamping (C26000 Brass equivalents) and cryogenic applications.

Electrical Optimization

With conductivity reaching 101% IACS, our 99.97% purity copper minimizes resistive losses in high-frequency data transmission and high-current power distribution systems, supporting the next generation of 5G and EV infrastructure.

🚀

Future Outlook: 6N Purity

Our technical roadmap includes the transition toward Ultra-High Purity (UHP) copper (99.9999%). This evolution is critical for quantum computing and high-resolution medical imaging where any impurity can lead to signal interference.

Macro Industry Solutions: Beyond the Material

New Energy Vehicles

Providing high-performance copper for inverters and charging ports. Our C14500 tellurium copper ensures efficient heat dissipation and low contact resistance.

Aerospace & Vacuum

Oxygen-free copper is essential for high-vacuum electronic devices. Its high vapor pressure resistance prevents metal evaporation under extreme conditions.

FAQ: Oxygen Free Copper Insights

What is the difference between 99.97% and 99.99% purity copper?
While 99.97% (C10200) is standard for most industrial applications, 99.99% (C10100) is the "Electronic Grade," further reducing silver and other trace impurities for sensitive electronics.
How does OFC prevent hydrogen embrittlement?
By removing oxygen, OFC prevents the formation of water vapor inside the metal during high-temperature brazing or welding, which would otherwise cause internal cracking.
Is tellurium copper better than pure copper for machining?
Yes. While pure copper is soft and "sticky" during cutting, our tellurium copper (C14500) offers an 85% machinability rating while maintaining 90%+ conductivity.
Do you support custom alloy development?
Absolutely. Our independent R&D team specializes in developing high-conductivity, high-strength copper alloys tailored to specific client requirements.
