Product Information

CW008A, also known as Cu-OF (Oxygen-Free Copper) or C10200, is a high-purity copper grade with a minimum copper content of 99.95% and extremely low oxygen levels (≤ 0.001%). This grade with low oxygen content offers the benefits of both Cu-ETP and Cu-DHP. Cu-OF (CW008A) is renowned for its exceptional electrical and thermal conductivity, excellent formability, and resistance to hydrogen embrittlement, making it ideal for electrical, electronic, and vacuum applications

Key Characteristics

  • Outstanding Electrical and Thermal Conductivity: Among the highest of all engineering metals.
  • Hydrogen Embrittlement Resistance: Safe for use in reducing atmospheres and high-vacuum environments.
  • Excellent Formability: Suitable for both hot and cold working.
  • Joining: Excellent soldering and brazing, good gas-shielded arc welding, fair oxy-acetylene welding.
  • Corrosion Resistance: Very good in most environments.

Applications

  • Electrical Industry: Busbars, transformer windings, switchgear, connectors, and high-performance cables.
  • Electronics: Semiconductor components, vacuum tubes, and precision connectors.
  • Vacuum and High-Purity Systems: Components for high-vacuum furnaces and scientific equipment.
  • Thermal Applications: Heat exchangers, radiators, and cooling systems.
  • Potable Water Systems: Pipes and fittings compliant with EU drinking water regulations

Cu-OF (CW008A) is listed in the European Positive List under Commission Implementing Decision (EU) 2024/367, ensuring compliance with Directive (EU) 2020/2184 for materials in contact with drinking water. This guarantees its suitability for hygienic and safe use in potable water systems.
