Graphite block is made of domestic petroleum coke, with carbon content above 99%. We have vibratedã??molded and isotropic graphite block. They are widely used in such fields as mechanical , electronics, chemical industry and other new industries. We can machine to specific shapes according to customers' requirements.
Industrial Minerals
The chemical properties of graphite are very stable, high temperature resistance, corrosion resistance, and good conductivity.Therefore, graphite can be used as refractory material, sealing material, conductive material, and is widely used in high temperature metallurgy, sand finding, paint lubricant, pencil lead, pigment, polishing agent, petrochemical industry, synthetic fiber, heater and other industries.
Natural graphite
UHP 400mm*1800mm UHP 450mm*1800mm Used in steel, cement and glass manufacturing, expanded graphite - based sealing gaskets, graphite grease, braid, brushes, brake lining, etc.
Vibrating,Extruded,Molded,Isostatic Graphite Block uses the particle size in 2 and 0.8 mm ,15�¼m and etc for different types of graphite blocks has advantages such as high temperature resistance, oxidation resistance, low content of impurities, single large size, low manufacturing cost advantages. Medium Grain Graphite has good mechanical, electrical and thermal properties, with low ash content. Machined parts, such as plates, bricks, discs, crucibles and sleeves can also be manufactured. Application:Solar photovoltaic, EDM, Semiconductor Metal Continuous Casting, Mold Industry, Precision Ceramic Sintering, High Temperature Corrosion Resistant Containers, Automobile Industry, Mobile Communication Industry, etc.
Graphite block is used in the fields of national defense, machinery, metallurgy, chemical industry, casting, non-ferrous alloys, and lightening, especially black carbon rods. It is also used in the fields of ceramics, semiconductors, medicine, environmental protection, laboratory analysis, etc. metallic material. When cutting steel, it is not necessary to use flammable and explosive gases like oxygen-acetylene flame cutting, which has low cost and safe operation. You can use arc cutting to process a variety of metals that cannot be processed by gas cutting, such as cast iron, stainless steel, copper, aluminum, etc., with high efficiency, and all can get more ideal results. Performance: The component is hard and brittle, has a small expansion coefficient, can withstand rapid cooling and heat, is not easy to deform, has good chemical stability, has strong acid resistance, does not react with strong acids, has poor alkali resistance, and can corrode at high temperatures.
Baked graphite block with following specifications: Apprant density: 1.6g/cmâ?º min. Specific resistivity: 2 5 u m max. Ash:1.0% max. Sulphur: 0.3% max. Size: 3150mm X 630mm X 600mm Customized production available, please enquire.
EDM is a process that high temperature is produced by direct electric discharge between work piece and electrode, and duplicate work piece under high temperature as per electrode shapes and accuracy. The work piece of EDM are usually with complicated shapes or high hardness which makes it difficult to mechanically machine. EDM becomes necessary process in metal molds making industries currently. Applications: Automotive Mould Industry Mechanical Metallurgy Light industry Electrical
