The rate of thermal conductivity of graphite products is a very important physical parameter in a variety of non-metallic materials in graphite products with anisotropic thermal conductivity of graphite products, but the rate has a unique feature: reach a maximum value at a certain temperature, but below or above this temperature thermal conductivity will decrease. There is no conversion to the graphite lattice of carbon raw materials or poor degree of carbon ink, thermal conductivity is much smaller. So although the specific heat of carbon and graphite is not large, but the thermal conductivity can be several times or even several times the gap. A lot of carbon and graphite products are good conductors of heat, while the other carbon materials with small thermal conductivity, can be used as high temperature insulation. This feature is now widely used in many fields.
How about the conductivity of graphite products? Here we give you analysis, you can learn from.
1、The speed is fast: the graphite discharge is 2-3 times faster than copper, the material is not easy to deform, and the advantage is obvious in the processing of the thin electrode.
2、Light weight: the density of graphite is only 1/5 of copper, large electrode discharge processing, can effectively reduce the burden of machine tools (EDM).
3、No burr: copper electrode after the end of the process, the need to manually remove the burr, and graphite processing without burr, which not only saves a lot of cost and manpower, but also easier to automate production.
4、Low cost: in recent years, copper prices continue to rise, and now, all aspects of the same price of graphite than copper, the price is relatively stable, short-term price fluctuations are relatively small.
