Description
CW101C Copper Rod — High-Purity OFE Grade for Advanced Electrical & Vacuum Applications
CW101C Copper Rod is Oxygen Free Electronic (OFE) copper with 99.99% copper purity and oxygen level below 5 ppm. It has a minimum electrical conductivity of 101% IACS (58.58 MS/m) and thermal conductivity of about 390 W/(m·K).
The material is suitable for vacuum electronics, semiconductors machining and high frequency transmission systems when the normal ETP copper cannot match the operating criteria. Dongguan Jiaye Dingsheng has more than 25 years of expertise in the copper alloy production industry, and strictly controls the dimensions and composition of every rods, and provides MTC certifications in accordance with EN 10204 3.1 for each batch.
What Is CW101C Copper Rod?
CW101C is the professional Copper grade of OFE according to the requirements of EN 12163 and EN 13601 with the copper purity above 99.99% and the trace impurities strictly controlled to avoid the inclusion of oxides.
This grade contains almost little cuprous oxide compared to regular ETP copper and avoids hydrogen embrittlement during high temperature brazing and annealing in reducing atmospheres. it reduces internal micro-cracking caused by oxide reaction, enabling stable structural performance under high-heat and reactive operating conditions.

Key Material Properties
Hydrogen embrittlement resistance: The absence of cuprous oxide in the material prevents internal steam generation during thermal processing, which supports safe brazing, annealing and welding.
Electrical performance: 101% IACS conductivity, reduces resistive heating and signal loss for use in high frequency and precision electronic equipment.
Good cryogenic ductility: Fully mechanical stable and conductive at ultra low temperature, suited for superconductor stabilisation and low temperature research equipments.
Application Scenarios
CW101C Copper Rod covers multiple high-precision industrial fields. It serves vacuum electronics parts including vacuum interrupters and waveguides, with low impurity volatility to avoid equipment outgassing failure. It acts as stabilization matrix for superconductor facilities to dissipate energy safely during quench events. It also fits semiconductor tooling components and high-temperature brazing assemblies, tolerating long-term thermal cycling and ensuring void-free welding joints.
CW101C vs. Standard ETP Copper
| Property | CW101C (OFE) | ETP Copper (C11000) |
|---|---|---|
| Copper Purity | ≥ 99.99% | ≥ 99.90% |
| Oxygen Content | < 5 ppm | 100–400 ppm |
| Electrical Conductivity | ≥ 101% IACS | ~100% IACS |
| Hydrogen Embrittlement Risk | None | High |
| Vacuum Application Suitability | Yes | Not recommended |
| Cryogenic Performance | Excellent | Moderate |
| Brazing / Welding Compatibility | All methods | Limited |
For general electrical wiring, ETP copper is sufficient. But for vacuum systems, semiconductor tooling, and precision brazing, the oxide content in ETP copper becomes a real liability. CW101C eliminates that risk entirely.

Frequently Asked Questions
Q1: What is the difference between CW101C and CW102C?
A1: CW101C has higher purity than CW102C at 99.99% and with <5 ppm oxygen. It is the material of choice for vacuum and high-precision electronic applications.
Q2: Can I use CW101C for welding and brazing?
A2: Yes. Its oxygen-free structure is suitable for TIG welding, electron-beam welding and all standard brazing processes, producing clean, pore-free connections.
Q3: What is the effect of temperature on its conductivity?
A3: Conductivity decreases with increasing temperature, just like in all copper. It has better conductivity than ETP copper and is stable at cryogenic temperatures.
Q4: Is special storage of the substance required?
A4: Surface oxidation is only on the surface, with no penetration within. For precise use, we suggest storing in low humidity or vacuum-packed conditions.
Q5: What documentation is given for shipment?
A5: Every order is supplied with comprehensive traceability, including EN 10204 3.1 MTC certifications for composition, conductivity and dimensional test data.
