Factory source Copper Foil Paper - Oxygen-Free Copper Wire High Purity And High Conductivity – Buck

Introduction

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.
