 1 GB TU2 oxygen-free copper rod Overview 
 No oxygen is also free of any residue of copper deoxidizer. But in fact contains a very small amount of oxygen and some impurities. According to standard requirements, oxygen free copper rod 
 Content of not more than 0.003%, the total impurity content of less than 0.05%, 99.95% purity copper. According to the oxygen content and impurities, oxygen-free copper rod is divided into I and II oxygen-free copper. One oxygen-free copper rod purity of 99.97%, oxygen content less than 0.003%, the total impurity content of less than 0.03%; II 99.95% purity oxygen-free copper rod, oxygen content less than 0.003%, the total content of impurities not more than 0.05%. TU2 is the main feature oxygen-free copper rod material in the oxygen content of the standard value is not greater than 10ppm, embodiments of the set value of 3.0 ± 0.7ppm. 

 (2) the name of imported materials C10200 oxygen-free copper rod 
 I and II oxygen-free copper rod with two types of grades are: TU1, TU2, oxygen content less than 0.003%, phosphorus deoxidized copper sub-deoxidized copper and manganese deoxidized copper are two kinds of oxygen content less than 0.001%, residual phosphorus 0.01% ~ 0.04%, manganese 0.1% residual 0.3%; 

 3 GB TU2 characteristics of oxygen-free copper rod 
 And low oxygen content, high purity, electrical conductivity. Excellent thermal conductivity, excellent ductility, low permeability, no "hydrogen disease" or little "hydrogen disease"; processing performance and welding corrosion. Cold are good . oxygen-free copper rod is quoted on the production of the oxygen content of less than 200PPM, a good lead on the general production of about 100 PPM, or national, general equipment, such as the Navy is also better to pull in more than 0.12mm If the foreign Outokumpu or Ni Huofu of equipment can be pulled 0.02mm, hypoxia plus gadolinium copper casting process to produce even now many companies for the U.S. Ganan SCR production line, the oxygen content is less than 400PPM stable quality, better pull over 0.08. Hypoxia should pull the copper is not good regeneration of copper, copper in Guangdong we called hypoxia, in fact, the low-oxygen copper rod production line and South are two concepts, this is a secondary copper smelting waste recycled without purification (with the cited Act, there are also hot with gadolinium law), resistance is not up to much bad pull impurities, generally only pulled 0.14mm. In fact, the South is the best line of low-oxygen copper production, quality, stability, and resistance pass, pull and stability. Oxygen-free copper rod on the cited method is low, suitable for transparent line, fine line drawing on the best use of foreign law cited equipment. Copper oxide is the production process, I can do better than others, regenerative oxygen-free copper rod copper wire better oxidation resistance, of course, the material is also different, the higher the oxygen content of the more easily oxidized, and is diffusible The key is to look at what the various manufacturers use technology to control it. 


 4 scope of the import C10200 oxygen-free copper rod 
 OFC (oxygen-free copper rod): purity of 99.995% copper. Generally used for audio equipment, vacuum electronic devices, cables and other electrical and electronic should be oxygen-free copper rod 
 With being. Oxygen-free copper rods which have LC-OFC (linear crystal oxygen-free copper rod or crystal oxygen-free copper rod): purity of 99.995% or more and OCC (single crystal oxygen-free copper rod): the highest purity in 99.996% or more, divided into PC-OCC and the UP-OCC and so on. Uses UP-OCC technology (Ultra Pure Copper by Ohno Continuous Casting Process) single-crystal oxygen-free copper rod manufacturing, non-directional, high purity, corrosion resistant, low electrical resistance wire suitable for making high-quality transmission of signals.
