One of the cost-effective ceramic parts3.. High hardness up to 1700 HV,4.Super compressive up to 2240 Mpa5. High heat resistance6. Good wear resistance7. High electrical resistivity8. High corrosion resistance9. Support customized specification, serviceThe description of alumina ceramic partsAluminum oxide (Alumina) has an extensive application due to its versatility and low cost of material than other advanced ceramics. Alumina offers high electrical insulation resistance, high-temperature resistance, strong hardness, wear resistance, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion.Our factory produces a selection of purity of alumina from 75% to 99.8%, all of the ceramic parts we supplied are with a dense body via dry pressing, hot pressing, ceramic injection molding, and ISO pressing. In order to achieve some special application for fitting, reducing the friction, increasing the insulation, we provide a serial of secondary processes after sintering, covering CNC machining, polishing, glazing, and metalizing.We manufacture a wide range of alumina ceramic rings, including ceramic tubes, ceramic rings, ceramic discs, ceramic rods, ceramic arms, ceramic wire guides. Whatever, it's a prototyping case, or high volume demand, we believe we are able to provide you a desirable solution. Typical ApplicationsThe application of alumina ceramic partsRemark:Alumina ceramic parts are widely used in the electronic, electrical, machinery, chemistry, ceramic seal, mineral, new energy, military, aerospace, almost all modern industries.Products category Remark:We produce a series of alumina ceramic products, including alumina metalized ceramics, ceramic substrates, ceramic wafers, ceramic guides, and so on.Product ParametersDatasheet 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.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 Why choose us?1.
