Difference between hypoxic copper rod and anaerobic copper rod

Low oxygen copper rod and oxygen copper rod difference low oxygen copper rod and oxygen copper rod because of the different manufacturing methods, resulting in differences, with their own characteristics.

1) About oxygen inhalation and removal and its existence state

2) The difference between hot rolling and casting structure

3) Inclusion, oxygen content fluctuation, surface oxides and possible differences in hot rolling defects

4) There are differences in toughness between low oxygen copper rod and no oxygen copper rod

Both can be drawn up to 0.015mm, but in the low temperature superconducting line, the low temperature grade oxygen free copper filament spacing is only 0.001mm.

5) There are differences in economy from raw materials of rod making to wire making

The manufacture of oxygen-free copper rod requires high quality raw materials. Generally, when drawing copper wire with diameter >1mm, the advantage of low oxygen copper rod is obvious, while the advantage of no oxygen copper rod is more superior to drawing copper wire with diameter <0.5mm.

6) The wire making process of low oxygen copper rod is different from that of no oxygen copper rod

The wire making process of low oxygen copper rod can not be copied to the wire making process of no oxygen copper rod, at least the annealing process is different. Because the softness of wire is greatly affected by the material composition and rod - making, wire - making and annealing process, it is not simple to say which is soft and which is hard for hypoxic copper or anaerobic copper.

The oxygen content and appearance of the copper rod are different because of the different technology of producing copper rod. Lead up the production of copper rod, appropriate process oxygen content below 10ppm, called anaerobic copper rod; Continuous casting continuous casting production of copper rod is hot rolling under protection conditions, oxygen content in the range of 200-500ppm, but sometimes as high as 700ppm above, under general circumstances, this method of production of copper appearance bright, sometimes also called light rod.
