Oxygen-Free Copper Wire High Purity And High Conductivity

Oxygen free copper wire refers to pure copper without oxygen and without any deoxidizer residue. copper wire made of pure copper,
But in fact it still contains a very small amount of oxygen and some impurities. According to the standard, the content of oxygen is not more than 0.003%, the total content of impurities is not more than 0.05%, and the purity of copper is more than 99.95%. Oxygen-free copper is divided into No. 1 and No. 2 oxygen-free copper. The purity of No. 1 oxygen-free copper reaches 99.97%, the oxygen content is not more than 0.003%, and the total impurity content is not more than 0.03%; Oxygen-free copper products are mainly used in the electronics industry. It is often made into oxygen-free copper plates, oxygen-free copper strips, and oxygen-free copper wires, with high electrical conductivity, good processing performance, welding performance, corrosion resistance and low temperature performance. Different countries have different standards for oxygen content.
