According to the oxygen content and impurity content, oxygen-free copper is divided into No. 1 and No. 2 oxygen-free copper. The purity of No. 1 oxygen-free copper reaches .%, the oxygen content is not more than .%, and the total impurity content is not more than .%. The purity of No. 2 oxygen-free copper reaches .%, the oxygen content is not more than .%, and the total impurity content is not more than .%. Oxygen-free copper has no hydrogen embrittlement, high electrical conductivity, good processing performance, welding performance, corrosion resistance and low temperature performance. The standards for oxygen content in different countries are not exactly the same, and there are certain differences.
(Oxygen-free copper) Metallic copper with a purity of. Generally used in electrical and electronic applications such as audio equipment, vacuum electronic devices, cables, etc.

Oxygen-free copper
Among them, there are (linear crystallized oxygen-free copper or crystalline oxygen-free copper) with a purity above .% and (single crystal oxygen-free copper) with the highest purity, above .%, and they are divided into .
Using single crystal oxygen-free copper made with advanced technology, it has no directionality, high purity, anti-corrosion, and extremely low electrical impedance, making the wire suitable for high-speed and high-quality signal transmission.
