1. Good machining performance
Compared with metal materials, graphite has lower density and excellent machining properties.
2.Thermal stability
Protected by an inert gas, he can work at temperatures of 3000 degrees or more.
3.The low inflation rate
Even in the case of rapid temperature rise, the low thermal expansion rate can guarantee that the graphite size remains unchanged.
4. Good chemical resistance
Graphite has good chemical stability at room temperature, such as acid resistance, alkali resistance and organic solvent resistance.
5.Good electrical and thermal conductivity
Because of its excellent thermal conductivity, graphite is ideal for some applications, such as heating.
6. High purity of molded graphite also has other excellent properties, such as:
-High strength
-ultra pure
-Anti-corrosion
-Low resistance
-Stable performance
- Environmental protection
