Product Description

Performance   
1. Good processing performance.
2. Compared with metal materials, graphite has a lower density and excellent mechanical processing performance.
3. Thermal stability: under the protection of inert gas, he can work at 3000 degrees or even higher.
4. Low expansion rate: even in the case of rapid heating, the low thermal expansion rate can ensure that the graphite size remains unchanged.
5. Good chemical resistance: graphite has good chemical stability, such as acid, alkali resistance and organic solvents at room temperature.
Applications
1.Bearings and seals in pumps.  Turbines and Motors.
2.Used in continuous casting systems for making shaped steel, cast iron, copper, aluminum.
3.Sintering molds for cemented carbides ,diamond tools,electronic components.
4.Electrodes for EDM.  Heaters.  Heat shields.   Crucibles.   Boats in some industrial furnaces
(such as furnaces for pulling monocrystalline silicon or optical fibers).
and so on.
