EDM graphite blocks are becoming more and more popular among our customers. EDM graphite is a new material. In recent years, with the development of China's industry, remarkable achievements have been made in science and technology. It has become the theme of The Times to create higher quality and lower cost in the field of precision mold industry. Therefore, graphite blocks for machining has become a new vane to look for newer graphite block material to replace copper electrodes in the industry. Therefore, the demand for EDM graphite blocks from our company is increasing in many EDM manufacturers.

Graphite is an allotroph of carbon, gray black, opaque solid, melting point of 3652℃, boiling point of 4827℃. Solid carbon graphite block, a stable chemical property, is corrosion resistance, and is hard to react with acid, alkali and other agents. Carbon graphite block burns in oxygen at 687℃ to form carbon dioxide. It can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. The graphite carbon block also can be used as an antiwear agent or lubricant. High purity graphite as a neutron decelerating agent in the atomic reactor, can be used to manufacture graphite crucible, electrode, brush, dry cell, graphite fiber, heat exchanger, cooler, arc furnace, arc lamp, pencil core, and so on.

Extruded graphite block, mainly used for molten iron with casting molds and graphite crucible furnace, powder metallurgy, sintering boat and tray, melting and alloying crucible, etc.

High purity graphite is graphite with carbon content greater than 99.99%, which is widely used in military industrial pyrotechnic material stabilizer, advanced refractory material in metallurgical industry and catalyst and additive in chemical fertilizer industry.

Artificial graphite is considered to be the most suitable material for the continuous or semi-continuous casting of non-ferrous metals. Production practice has proved that using graphite mould continuous casting industry, because of its good performance of thermal conductivity, thermal conductivity performance determines the speed of solidification of the metal or alloy), mold good self-lubricating performance factors, not only make the casting speed, and due to the size of the graphite blocks for casting precision, smooth surface, uniform crystal structure, can be directly for the next working procedure of processing. This not only greatly improves the rate of finished products, reduces the loss of waste, but also greatly improves the quality of products.

Isostatic graphite blocks are mainly used in solar single, polycrystalline thermal field, semiconductor single crystal thermal field, graphite mold processing, insulation materials (solidified felt, carbon felt, graphite soft felt), graphite electrode (RP/HP/UHP), graphite special-shaped parts, graphite carburizer, etc.
