Product Description Product DescriptionHigh Precision Wear Resistant Polished 99% Alumina Ceramic PistonProduct Characteristics1. High hardness, it is can be up to 1700 HV, and Super compressive strength up to 2240 Mpa2. They offer different grade dimensional accuracy per sintered only, precision machining 3. They are more cost-effective ceramic parts with equivalent performance among all other technical ceramics4. High heat resistance: Alumina ceramic parts offer excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential.5. Good wear resistance: it is an ideal choice for ceramic wear parts in the high abrasive industry6. High electrical resistivity: used in all-electric products, electric heating products, and wear-resistant machinery parts.7. High corrosion resistance: It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.8. We support a variety of customized alumina ceramic parts base on customer's drawing, sample, or reference parametersPruduct ApplicationCeramic plungers are commonly used in the machinery manufacturing and chemical industries for sealing and fluid control.In the machinery manufacturing industry, ceramic plungers are widely used in precision machinery such as high-pressure injection pumps, plunger pumps, automobile engines and aircraft engines to improve mechanical sealing and wear resistance.In the chemical industry, ceramic plungers are often used in chemical reactors and piping systems for high temperature and corrosion resistant media.Technical DatasheetDatasheet of technical ceramic materialsPropertyUnitsMaterials99.5% Al2O399% Al2O395% Al2O3ZrO2Si3N4Densityg/cm3≥3.85≥3.80≥3.60≥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·k)302924315~20Volume 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 Our AdvantagesWhy choose us?1.15 years of manufacturing experience in OEM, ODM, and professional management & production team 2.
