We all know that graphite products are often used in life, in which graphite electrodes are widely used, and compared with copper motors, what are the advantages of graphite electrodes?
1, Fast: Graphite discharge is 2-3 times faster than copper, the material is not easily deformed, the advantages of thin rib electrode processing are obvious, but the copper electrode is easy to deform.
2, Llight weight: the density of graphite only 1/5 of copper, large electrode discharge processing, can effectively reduce the burden of machine tool (EDM).
3, No burr: copper electrode in the end of processing, but also need to manually remove burrs, and graphite processing without burrs, which not only save a lot of costs and manpower, but also easier to achieve automated production.
4, Low cost: As a result of rising copper prices in recent years, now, all aspects of same-sex graphite prices lower than copper, relatively stable price, short-term price fluctuations relatively small.
The thermal conductivity of graphite products is a very important physical parameter, the graphite products in various non-metallic materials have anisotropy, but the thermal conductivity of graphite products has a unique characteristic: at a certain temperature to reach the maximum value, but lower or higher than this temperature when the thermal conductivity will be reduced. It has not been converted to graphite crystal lattice of carbonaceous raw materials or poor degree of carbon, thermal conductivity is much smaller. Therefore, although the specific heat difference between carbon and graphite is small, the thermal conductivity can be several times or even dozens of times times the gap. Many carbon and graphite products are a good conductor of heat, while another carbon material has a very small thermal conductivity, which can be used as a high-temperature insulator. This feature is widely used in many areas today.
