The final copper wire product is improved by reducing the area reduction rate between annealing to 90%. There are several conductive metals that are lighter than copper, but they carry the same amount of current, and they require a larger cross-section, so if space saving is required, these metals are not desirable.. Processing of copper rods and copper wires In the 1970s, almost all copper was processed in batches. 1. The advantages of continuous casting are that the smaller impurities are separated, the copper oxide particles on the surface are reduced, the steel content is reduced in the process of touching the roll, all welds are almost prevented, and the overall production cost is reduced. Next, put it in 10% sulfuric acid to remove the oxide on it,and form a longer coil by connecting one end to the other. There are about fifty different forging alloys with a minimum copper content of 99. For a certain high-quality application, mechanical trimming is generally required to remove the multi-layer metal shovel on the surface. The most harmful of these ingredients can reduce the electrical conductivity, improve the mechanical strength of the front, prevent recrystallization, and sometimes cause hot embrittlement during the hot pressing process of processing copper rods. This article first Copper tape for computer components on the reasons for doing so, and also paid special attention to some basic refinement guidelines. In addition to surface reduction, the metallographic structure may also change, which then weakens the mechanical properties of the copper wire. Intentionally, oxygen and copper are made into alloys, which are used as purifiers to dissolve hydrogen and hydrogen, and then form two gases, H2O and SO2, during melting. Copper is an excellent conductor in particular.
