The electric carbon products application and choosing | |||||
Grade | Brand | Process of manufacture and characteristic | Usage | Friction mates | |
Hard carbon | M126 | Impregnation with pitch once | High hardess, wear resitance, high mechanical strength, corrosion resistance | Bearings, hushes, pistonrings, gide rings etc | Tingsten carbide, ceramices, wear resistance cast iron etc |
M104 | |||||
Electro graphite | M252 | M152 after graphitization treatment | Good self-lubricating property, with fair mechanical strength, high prsistance to high temperature and good processibility | End seal, bearings, piston rings etc | Staninless steel, case hardening steel, tungsten carbide, bronze etc |
M204 | M104 after graphitization treatment | ||||
M233 | Impregnation with pitch four times, baking and graphitization | ||||
Impregnation with epoxy resin | M104H | M104 after restrengthening treatment with epoxy resin | Good sraling property, mechanical strength and wear-resistance property better than those of electrographitr good machining property | End seal, expansion ring seal, sealing vans, axial seal, piston rings, bearongs etc | Tungsten carbide, staninless steel, bead welded alloy, hard metal coating etc |
M126H | M126 after restrengthening treatment with epoxy resin |
