Molded Graphite Block

Product Description All high purity Molded Pressed Graphite have individual properties that will help you to choose the perfect grade that best suits your needs. Molded Pressed Graphite provides an extremely wide range of properties in terms of mechanical strength, friction, density, hardness and conductivity, which is even further enhanced by impregnation with resin or metal. Due to their fine grain size and homogeneous structure, it can often replace Isostatic Graphite if dimensions is not taken into consideration.   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.   Specifications Item Unit Molded graphite Grain size μm 15-40 Bulk density g/cm3 1.5-1.9 Specific resistance μΩ.m 7-15 Bending strength Mpa 15-50 Compressive strength Mpa 30-100 Shore hardness   20-80 Ash ppm 20-800                       Popular Sizes of Graphite Block Molded Graphite Block Round Block   Square Block Ф55*120   300*200*120 Ф65*120   300*250*120 Ф65*135   330*260*160 Ф70*135   345*345*165 Ф75*120   350*270*150 Ф105*160   370*280*150 Ф110*160   420*310*140 Ф110*255   420*310*150 Ф145*260   420*310*160 Ф160*255   420*310*180 Ф180*255   420*310*200 Ф190*410   400*400*300 Ф225*260   500*300*200 Ф240*410   650*210*150 Ф300*255   650*500*200 Ф330*255     Ф480*400     Note: Special sizes are available according to customer’s requirement.
