 1 GB TP1 phosphorus deoxidation copper Overview 
 TP1 phosphating oxygen copper welding and cold bending performance is good, generally no "hydrogen disease" tendency can be processed in a reducing atmosphere, the use of, but not in the oxidizing atmosphere in the processing, use. TP1 TP2 less than the residual phosphorus, so the electrical conductivity, thermal conductivity higher than TP2. TP1 and TP2 mainly in pipe applications, you can board, with or rod, wire supply. Ordinary copper or carbon monoxide in hydrogen when heated in reducing atmosphere, hydrogen or carbon monoxide is easy and cuprous oxide grain boundaries (Cu2O) effect, resulting in high pressure steam or carbon dioxide gas, copper can break. This phenomenon is often called copper the "hydrogen disease." Insoluble in water vapor generated by copper along grain boundaries and overflows Splitting between grains, after cooling to form voids in the grain boundary, in the copper can be seen protruding on the surface or in the internal formation of vesicles micro-cracks, resulting in copper brittle, lower intensity, resulting in chronic leakage, a phenomenon known as the "hydrogen disease." Therefore, copper can not be hydrogen annealing, brazing, or seal, you need to vacuum heat treatment. Low-oxygen copper phosphate oxygen, it can be heat treated in hydrogen does not occur "hydrogen disease."

 Abbreviation: TP1, melting high purity raw materials, to produce oxygen in molten copper using oxophilic phosphorus (P) oxygen to the oxygen content decreased to less than 100ppm. 

 3 GB TP1 features phosphorus copper deoxidation 
 Improve the ductility of copper after deoxidation, corrosion resistance, thermal conductivity, weldability, pull processing, in the heat of the phenomenon of hydrogen embrittlement does not occur. Phosphating oxygen copper wire, copper off by phosphorus to the oxygen inside, and now is used with multi-TP2 grade, the copper content of 99.90%, phosphorus content is between 0.015 ~ 0.040%. The conductivity decreased, but its better welding performance. Phosphating oxygen free copper wire than good, because the phosphating process is oxygen in oxygen-free copper wire on the basis of the phosphate, reducing the contact with oxygen, increasing copper oxidation and prolong life.
