Different Sizes of Graphite for EDM

different sizes of graphite for EDM:   1. High density / Fine grain size / High purity / High strength / Low specific resistance / Ease of precise machining2. Excellent thermal shock resistance to high temperature and oxidation / Good anticorrosion .Application:Semiconductor (Monocrystalline Silicon) / Vacuum furnace / Continuous casting / Sealing products / Space & medical industry / Forge moulds EDM.Heaters / Heat shields /Electronic tube anodes / Melting and sinteringmoulds for Pottery & Electronic Products & Cemented Carbide &  Diamond &  Aluminium & Copper & Other metals/ Etc.MOLDEDM 1M 2Bulk Density MIN(g/cm3)1.781.85 Ash Content(PPM)500-1000500-1000SHORE  HARDNESS4045ELECTRICAL RESISTVITY(μ.Ω.m)≤12≤12FLEXURAL  STRENGTH(MPa)30--3535--45COMPRESSION STRENGTH(MPa)50--5560--82MAX GRAIN SIZE(μm)43μm43μmCOEFFICIENT OF THERMAL EXPANSION(100-600ºC) (mm/ºC)4.5×10-64.5×10-6Note:Ash content of all grades can be purified to 20 PPM.Special property requirement specially produced.Size:RodsDiameterLengthSize Range0-1300mm0-2000mmStandard Size110-500mm180-400mm       BlocksLengthWidthThicknessSize Range0-900 mm0-400 mm0-320 mmStandard Size200-900 mm125-400 mm53-320 mmLarger size specially pressed. Smaller size further machined.Machined parts done to drawingsAnticorrosion cover available(SiC Cover, Pitch Cover, etc)  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
