Performance difference between low oxygen copper rod and oxygen free copper rod

The oxygen content and appearance of the copper rods produced are different due to the different processes of the two. The copper rod produced by upward drawing is called oxygen free copper rod when the oxygen content is below 10ppm; Copper rods produced by continuous casting and continuous casting are hot rolled under protective conditions, and the oxygen content is within the range of 200-500ppm, but sometimes it is also high

Can't find the reason for copper wire oxidation? You may have overlooked these common mistakes!

The atomic number of copper is 29, belonging to the transition metal, with a density of 8.92g/cm3 and a melting point of 1083.4 ℃. It has good thermal conductivity and electrical conductivity. However, in humid air, the copper surface reacts with oxygen to produce Cu2 (OH) 2CO3, or copper green. Usually, copper oxidation in cable manufacturers shows that the surface is blackened. It is this copper conductor
