High Performance Oxygen-Free Copper from Trusted China Suppliers and Factory

Oxygen-free copper, also known as oxygen-free copper, is a high-purity form of copper that contains no oxygen and no residues from deoxidizers. Despite production limitations that may introduce trace amounts of oxygen and some impurities, industry standards dictate that oxygen-free copper must have an oxygen content below 0.003% and a total impurity content under 0.05%, ensuring a copper purity of over 99.95%. In China, suppliers classify oxygen-free copper into two main grades: No. 1 (C10100) and No. 2 (C10200). No. 1 oxygen-free copper boasts an impressive purity of 99.97%, with oxygen and total impurity levels not exceeding 0.003% and 0.03%, respectively. On the other hand, No. 2 oxygen-free copper maintains a purity of 99.95%, with permissible oxygen and impurity levels of 0.005% and 0.05%, respectively. Our factory offers premium-grade oxygen-free copper products suitable for various applications, ensuring quality and consistency for our clients
