Product Description China Manufacturer Industrial Advanced ZrO2 Zirconia Al2O3 Alumina Structural CeramicsThe specification of technical ceramic partsOption Materialsalumina, zirconia, silicon carbide, silicon nitride, steatite optionalOuter diameter 0.5 ~800 mmLength1~1000mmRoughnessTo be Ra0.05Surface treatmentPolished, Glazed, Metalized availabilityCosmeticSmooth surface without contamination, deformation, and crackThe accuracy achieved after precision machining(1) Axis: roundness 0.002 mm, concentricity 0.002 mm, smoothness Ra0.1;(2) Hole: the minimum processing hole diameter is 0.2 mm and the depth is up to 6mm;(3) Slot: min. value to be 0.1 mm of narrow groove, and grooves with custom shapes;(4) Plane: 0.1mm sheet with minimum processable thickness, parallelism 0.001mm, measurement tolerance 0.001 mm, finish Ra0.1; (5) Thread: The minimum machinable M2 internal thread, the accuracy of GB-7h, the external thread size is not limited, the accuracy is GB-6g.The main characteristics of the technical ceramic parts1. They offer different grade dimensional accuracy per sintered only, precision machining 2. They are more cost-effective ceramic parts with equivalent performance among all other technical ceramics3.. High hardness, it is can be up to 1700 HV, and Super compressive strength up to 2240 Mpa3. 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.4. Good wear resistance: it is an ideal choice to wear parts in the high abrasive industry5. High electrical resistivity: used in all-electric products, electric heating products, and wear-resistant machinery parts.6. 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.7. We support a variety of customized alumina ceramic parts base on customer's drawing, sample, or reference parametersThe 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.The 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.The gallery of other alumina ceramic partsRemark:We produce a series of alumina ceramic products, including alumina metalized ceramics, ceramic substrate,ceramic wafer, ceramic guides, and so on.Datasheet 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?1.10+ years of manufacturing experience in OEM, ODM, and professional management & production team 2.
