What are the differences between domestic and imported graphite? Who can tell me? What are they used in?
Domestic graphite for large die EDM, because the price has advantages relative to imported graphite, so made in China for mold electrode roughing,
The import of fine graphite particles, the surface of the products out of the relatively smooth, no large grains of sand hole, suitable for precision EDM, imported graphite can do bone and groove of 0.2-0.3, after the discharge is not easy.
Domestic graphite and imported density is not the same, Shaw hardness is not the same, domestic graphite particles than the import of graphite to be much larger
