Among the three production methods of copper tube， the oxidation method is the most. Because as long as the metal copper is oxidized by the anode and the copper ion of the anode is attached to the tube material， the copper tube can be produced. Thisthod is also the most common method to produce copper materials. It has not only been used for a long time， but also has a mature technology， which is to produce copper tubes through oxidation reaction. This production method is the main production method of copper tubes in China.

The production method of soft copper tube is basically the same as that of hard copper tube， that is， the annealing process is added compared with the hard copper tube. Annealing of copper tubes means that they are calcined in a high temperature furnace to change the arrangement of the elements in the copper tubes. However， after annealing the copper tubes will become soft，센다 이 공항304 스테인리스 강판， which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.
품질 파일According to * * new data， in September ， Chinas imported iron ore * * * broke through the million ton mark， reaching million tons， a record high; From January to September， Chinas iron ore import increased by % to million tons， and the annual import volume is expected to exceed billion tons. However， judging from the shipment of imported ores after the National Day， due to the rapid declinecline in iron ore prices， the iron ore price index once fell below $， which reduced the enthusiasm for the shipment of imported ores. In addition， and the supply of some domestic mines has been greatly affected. The current operating rate of domestic mines is percentage points lower than the previous peak， which is likely to decline further in the future.
