oxygen-free copper tube

① Oxygen-free copper tube, also known as oxygen-free copper seamless tube, is a high-purity copper tube produced through a specific production process that effectively removes trace impurities from the copper during the smelting process, resulting in a purity of over 99.95%. This copper tube also contains an extremely low oxygen content and is highly valued among metal materials for its high purity, excellent electrical and thermal conductivity, and wide range of applications. It is primarily used in power transmission, electronic equipment manufacturing, thermal equipment, the chemical industry, and construction, among other fields.

Performance advantages of oxygen-free copper tube

  • High purity: The purity of oxygen-free copper tubes is very high, usually the oxygen content does not exceed 20ppm, and the copper content is higher than 95%. Its material purity is extremely high and has excellent electrical and thermal conductivity;
  • High conductivity: The conductivity of oxygen-free copper tubes is close to that of pure copper, with a conductivity generally above 98%, making them an ideal conductive material. They are widely used in power transmission and electronic equipment manufacturing.
  • Easy processing: Oxygen-free copper tubes have good processing performance and can be processed through complex processes such as welding, cutting, and bending, making them easy to use in various equipment and devices;
  • Corrosion resistance: Oxygen-free copper tubes have good corrosion resistance to a variety of acid, alkali, salt and other chemical media, and can maintain their performance and appearance for a long time. They are widely used in chemical, petroleum and other fields;
