Good machinability: compared with metal materials, graphite has lower density and excellent machinability. 2. Thermal stability: under the protection of inert gas, it can work at a temperature of 3000 degrees or even higher. 3. Low expansion rate: Even in the case of rapid heating, low thermal expansion rate can ensure that the graphite size remains unchanged. 4. Good chemical resistance: at room temperature graphite has good acid resistance, alkali resistance, organic solvent resistance and other good chemical stability. 5. Good electrical and thermal conductivity: Because of its good thermal conductivity, graphite is an ideal material for certain applications, such as heating parts. Application: Single crystal furnace, polycrystal furnace, continuous casting mold, electric discharge, electron sintering, semiconductor, vacuum furnace, heat treatment,. It is precisely because of this series of excellent properties, isostatic graphite in metallurgy, chemistry, electrical, photovoltaic, solar, energyaerospace and atomic energy industry and other fields have been widely used, with the development of science and technology, application field is still expanding.
