 1 GB TU1 oxygen-free copper with an overview of 
 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 with oxygen 
 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 is divided into I and II with oxygen-free copper belt. One oxygen-free copper with a purity of 99.97%, oxygen content less than 0.003%, the total impurity content of less than 0.03%; II oxygen-free copper with a purity of 99.95%, oxygen content less than 0.003%, the total content of impurities not more than 0.05%. 

 (2) the name of imported materials with oxygen-free copper C1020 
 Oxygen-free copper with I and II are two grades were: TU1, TU2, oxygen content less than 0.003%, phosphorus deoxidized copper deoxidized copper sub-deoxidized copper and manganese are two kinds of oxygen content less than 0.001%, residual phosphorus 0.01% ~ 0.04%, manganese 0.1% residual 0.3%; 

 3 GB with the characteristics of TU1 oxygen-free copper 
 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 with a lead 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 with oxygen on low-lead method, 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 with a 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 with oxygen-free copper imports C1020 
 OFC (oxygen-free copper belt): purity of 99.995% copper. Generally used for audio equipment, vacuum electronic devices, should be oxygen-free copper cable and other electrical and electronic band 
 With being. In which oxygen-free copper with another LC-OFC (linear crystal oxygen-free copper with or without crystal oxygen-free copper): purity of 99.995% or more and OCC (with single-crystal oxygen-free copper): purity of the highest in more than 99.996%, divided into PC-OCC and the UP-OCC and so on. Uses UP-OCC technology (Ultra Pure Copper by Ohno Continuous Casting Process) made with single-crystal oxygen-free copper, non-directional, high purity, corrosion resistant, low electrical resistance wire suitable for making high-quality transmission of signals.
