Isostatic Graphite Block

Product Description Iso-Molded Graphite, also named Isostatically Pressed Graphites or Isostatic Graphite、isotropic graphite. It is produced by the method of Cold Isostatic Pressing (CIP). Graphite is iso-statically pressed is because it allows for uniform properties in all grain directions. This differs from extruded which is pushed through a die and has varying properties in different grain directions. Iso-Molded Graphite is used for specific applications where uniform is required. DJX Graphite obtain a high finished product yield rate due to our unique process and quality control, this enable us to produce high quality consistent isotropic graphite. Features 1.Good Machinability Compared with metallic materials, the bulk density of graphite is lower. It has excellent mechanical machining properties. 2.Strong Thermal Stability It is possible to be used even at 3000℃ in inert atmosphere or more. 3.Low Expansion Ratio Low Thermal expansion ratio will ensure dimensional stable, even rapid change in temperature. 4.Excellent Chemical Resistance Graphite has good chemical stability at room temperature. Resistance to acid, alkali, and organic solvents. 5.Excellent Electrical Conductivity and Thermal Conductivity With strong thermal resistance, which means graphite is the ideal material for certain applications like heating element.
