Product Description High Precision Wear Resistance 95% 99% Alumina Ceramic Seal FaceThe main features of the ceramic seal face1. Superb chemical stability against hot strong acid and alkali and free of rust forever2. Excellent wear-resistance and abrasion resistance, over 276 times than stainless steel3. Perfect sliding surface quality: diamond-like surface, the roughness to be Ra0.14. High-temperature resistance, stand with over 1500oC free of deformation 5. Exceptional hardness, the physical hardness is up to 1700MPa6. Great mechanical properties, hardness, compressive and flexural strength7. Precise and consistent dimensions every batch via fine grinding, CNC machining8. Eco-friendly and safe, the material meets FDA, LFGB completely9.Stable breaking strength, and less variance in figure or dimensionThe description of the ceramic seal faceAlumina ceramic seal face is characterized by its extremely high strength, wear resistance, low friction, and chemical stability. The outstanding surface quality (diamond polished surface )on both sides makes it sealing performance as desired.Due to alumina's versatile features, alumina ceramic seal ring could work with various severe service environments well, even if under hot strong acid and alkali, high temperature, high pressure, high voltage / current status. It has a super long service cycle in comparison with metal mechanical seals and reduces the time of maintenance The ceramic seal ring plays a key role in water, oil, gas sealing system, we always ensure that we manufacture best-quality products through strict quality control in every process, we introduced KPI into our manufacturing flow chart and keep all batches with consistent dimensions. With over 15 years of manufacturing experience for ceramic seals, we have been supplying a variety of standard components, also we support various customized needs per your technical drawings, specification or practical samples.The specification of the ceramic seal face RoughnessFine polishing better than Ra0.3, diamond polishing better than Ra0.02DimensionThe max. outer diameter up to 500mmOther parametersFlatness to be 0.002mm, perpendicularity: 0.005mm, Parallelism : 0.002mmNominal toleranceSize less than 10mm with 0.10mm, size over than 10mm with 1% of dimensionsPrecision processPolishing, fine grinding, CNC machiningApplication of ceramic sealsCeramic seal discs are widely used in a variety of water faucet, water tap, sanitary sealing system, regulating system, sealing valves, water / oil / gas pump, and so on.Technical Datasheet of the ceramic sealsPropertyUnitsMaterials99.5% Al2O399% Al2O395% Al2O3ZrO2Si3N4Densityg/cm3≥3.90≥3.85≥3.65≥6.0≥3.2Water absorption%00000HardnessHV17001700150013001550Flexural strengthMpa≥379≥338≥320≥1200≥600Compressive strengthMpa≥2240≥2240≥2000≥1990≥2500Fracture toughnessMpa m1/24-54-53-46.5-86Max. service temperature(Non-loading)oC16751600150010001200CTE (20-800oC)1×10 -6 /oC6.5~8.06.2~8.05.0~8.08.0~9.53.1Thermal shockT(oC)≥250≥200≥220≥300≤1000Thermal conductivity(25oC)W/m.k302924315~20Volume resistivity (25oC )ohm.cm>1 x 10 14>1 x 10 14>1 x 10 14>1 x 10 11>1 x 10 12Insulation strengthKV/mm19181817 Dielectric constant(1Mhz)(E)9.79.59.529 Company ProfileJinghui Ceramic is a professional manufacturer of ceramic seals and has a complete and scientific quality management system.
