Purity 99.99% (4N) - Oxygen content below 10 ppm!
We handle "oxygen-free copper" with a copper purity of 99.99% and an oxygen content of less than 10 ppm, which is nearly zero. By using raw materials (electrolytic copper) with minimal impurities and preventing oxidation during the dip-forming system manufacturing process, we produce high-quality copper with an oxygen content far below 10 ppm. Please feel free to contact us if you have any requests. 【Features】 ■ High conductivity due to high purity ■ Resistant to hydrogen embrittlement ■ Excellent workability with minimal copper powder *For more details, please download the PDF or contact us.
