Graphite
Cylindrical isostatic graphite block for sales
1.The isotropic graphite is made from the raw materials of high quality pitch, petroleum coke and other aggregate and binding materials, through the processing of grinding, kneading, second grinding, isotropic forming, baking, impregnation with pressure, second baking, graphitization in high temperature, refinement etc.
2.GOOD CHARACTERS:
Good performance of electrical conductivity and thermal conductivity, high density, good corrosion resistance, thermal shock resistance, thermal stability, high mechanical strength, low permeability, and good oxidation resistance,good lubrication,fine grain,large size, etc.
3.APPLICATIONS:
Isotropic graphite is widely used in the fields of semiconductors, solar & photovoltaic, EDM processing, aerospace & defense, metal continuous casting and other industries.for EDM, for glass and ceramic industry,etc.
