Isostatic Graphite Raw Material Features 



Good processability


Compared with metal materials, graphite has lower density and excellent machinability.


Thermal Stability


Under the protection of inert gas, he can work at 3000 degrees or higher.


Low expansion rate


Even in the case of rapid temperature rise, low thermal expansion can ensure that the graphite size remains unchanged.


Good chemical resistance


Graphite has good chemical stability at room temperature, such as acid resistance, alkali resistance and organic solvent resistance.


Good conductivity and thermal conductivity


Because of its good thermal conductivity, graphite is an ideal material for some applications, such as heating elements.


Isostatic graphite also has other good properties, such as:


High strength


Ultrapure


Corrosion resistance


Low resistance


Stable performance


Environment protection


Application

Crucibles, casting molds, resistance heating elements, channels, parts for heat exchangers, furnace linings, head electrodes for Acheson furnace, anode for metal electrolysis, boats and trays for sintering, heat shields and covers of furnace, and etc.
