Descripción del producto

Fine grain and large size high pure graphite block

Isostatic graphite is a new type of graphite material developed in the ***0s and has a series of excellent properties. For example, isostatic graphite has good heat resistance, and its mechanical strength does not decrease but increases with increasing temperature in inert atmosphere, reaching its highest value at about ***0 ℃. Compared with ordinary graphite, the structure is fine and dense, and the uniformity is good. The coefficient of thermal expansion is very low and has excellent thermal shock resistance. Isotropy; Strong chemical corrosion resistance, good thermal conductivity and electrical conductivity; has excellent machining performance.

Five Star Carbon has the advantages of small resistance coefficient, high temperature resistance, corrosion resistance, oxidation resistance, good thermal shock resistance, low conductivity, thermal expansion coefficient, self lubrication, easy precision machining, etc. It is an ideal graphite anode and grid for inorganic nonmetal crucible boat, heater for single crystal furnace, EDM graphite, sintering mold, tube anode, metal coating, graphite crucible for semiconductor technology, emission tube, thyratron and mercury arc rectifier, etc.

 Five star carbon focus on the different parameters and product performance of isostatic pressing block according to different application fields, the customers can select their required materials.For example, WX - 7, WX - 8 and WX - *0 have the characteristics of high density, high compressive strength, high resistivity, large Shore hardness, large and stable coefficient of thermal expansion, small granularity, low ash content and so on, and are recommended for use in EDM and photovoltaic industries. WX - 6 has the characteristics of high density, high strength, high thermal conductivity, large coefficient of thermal expansion, low particle size and low ash content. It is recommended to be used in metal continuous casting, high temperature casting and metal sintering industries.

Therefore, we can select the most suitable materials for our customers, produce the highest quality products, and at the same time, save the cost to the greatest extent.So that both sides can achieve win-win cooperation and establish a long-term cooperative partnership.
