Product Details

Good Quality Flat Copper Strip C1100 Oxygen-Free Pure Copper Red Copper Coil For Transformer

Oxygen content is one of the most important properties of oxygen free copper. Because the amount of oxygen and copper is very small, oxygen in oxygen free copper actually exists in the form of Cu2O. At high temperatures, hydrogen diffuses through the copper at great speed, encounters Cu2O and reduces it, producing large amounts of water vapor. The amount of water vapor is proportional to the oxygen content of copper. For example, after annealing of 0.01% copper containing oxygen, 14cm3 water vapor will be formed in 100g copper. This water vapor cannot be dispersed through dense copper, so in the presence of Cu2O, there will be thousands of mpa of pressure, which will cause copper destruction, brittle cracking and loss of vacuum density. Therefore, oxygen content must be strictly limited.
