Extruded Graphite refers to graphite with a carbon content of >99%. 
It is suitable for powder metallurgy, electronics, machinery, molds, cathode materials, sewage treatment, non-ferrous metals, chemicals, new energy, photovoltaics and other industries.

Characteristics of graphite:

High temperature resistance: The melting point of graphite is 3850±50℃, and the boiling point is 4250℃. Even after being burned by an ultra-high temperature electric arc, the weight loss is very small, and the thermal expansion coefficient is also very small. The strength of graphite increases with the increase of temperature. At 2000℃, the strength of graphite doubles.

Electrical and thermal conductivity: The electrical conductivity of graphite is one hundred times higher than that of general non-metallic minerals. Its thermal conductivity exceeds that of metal materials such as steel, iron, and lead. The thermal conductivity coefficient decreases with increasing temperature, and even at extremely high temperatures, graphite becomes an insulator. Graphite can conduct electricity because each carbon atom in graphite only forms three covalent bonds with other carbon atoms, and each carbon atom still retains one free electron to transmit charge.

Lubricity: The lubricity of graphite depends on the size of the graphite flakes. The larger the flakes, the smaller the friction coefficient and the better the lubricity.

Chemical stability: Graphite has good chemical stability at room temperature and is resistant to corrosion by acids, alkalis and organic solvents.

Plasticity: Graphite has good toughness and can be ground into very thin sheets.
