High Temperture Corrosion Resistant Zirconium Oxide Ceramic Zirconia Bushing¹

Product Description High Temperture Corrosion Resistant Zirconium Oxide Ceramic Zirconia Bushing The Prime Characteristics1. High density:  over 6 g/cm3, which makes it the densest body of the ceramic products2. High hardness: over 9 on Mohs scale, diamond being 10, with a satin-smooth surface finish3. High toughness: over 1200 MPa, approx. 4 times in comparison with 95% alumina4. Excellent wear resistance, it's much better than aluminum oxide ceramics with a longer life cycle5. Low thermal conductivity:  less than 3 W/m.k at ambient temperature, so it's an ideal thermal material6. Good chemical and corrosion resistance, it's equivalent to above 99% alumina The specification Material optionZirconia (ZrO2),  Alumina(Al2O3), Silicon carbide(SiO2), Silicon nitride(Si3N4)Forming methodsDry pressed, Ceramic injection molding, Hot pressed, ISO pressedSpecificationOD can be from 1 to 50mm, length can be from 10mm to 800mmPrecision processingCNC machining, Precision grinding, Polishing, Lapping, ToleranceThe tolerance of OD and ID can be 0.001mm,  the tolerance of length can be 0.001mmKey parametersRoughness to be 0.02mm, Parallelism to be 0.001mmSurface qualityFree of cracks, foreign contamination, mirror surface better than Ra0.1Product DescriptionZirconia ceramic parts are made of zirconium oxide ceramics, a kind of strongest technical ceramic material with exceptional strength, high toughness, and superb reliability. These outstanding characteristics result in excellent resistance to wear and corrosion.We have been offering a selection of partially stabilized zirconia, including Y-TZP( yttria-stabilized), MSZ ( magnesia stabilized ), and CSZ- (ceria stabilized). Each stabilized zirconia provides unique and specific properties that meet the demands of extreme applications found in many industries.With our production capability through CNC and precision grinding machines,  we can provide many different levels of precision zirconia ceramic parts to meet customers' high-precision assembly needs.The gallery of zirconia ceramic parts Technical Datasheet PropertyUnitsMaterial 99.5%alumina99%alumina95%aluminaZrO2(Y-TZP)ZrO2(TTZ)Densityg/cm3≥3.85≥3.80≥3.60≥5.95≥5.72Water absorption%00000HardnessHV1700170015001300900Flexural strengthMpa≥379≥338≥320≥1200≥1200Compressive strengthMpa≥2240≥2240≥2000≥19901750Fracture toughnessMpa m1/24-54-53-46.5-811Max. servicetemperatureoC1675160014501000 CTE1×10 -6 /oC6.5~8.06.2~8.05.0~8.08.0~9.510.2Thermal shockT(oC)≥250≥200≥220≥300350Thermal conductivity(25oC)W/m.k30292433Volume resistivityohm.cm     25oC>1 x 10 14>1 x 10 14>1 x 10 14>1 x 10 11>1 x 10 11300oC1 x 10 128 x 10 1110 12 -10 131 x 10 101 x 10 10500oC5 x 10 102 x 10 91 x 10 91 x 10 61 x 10 6Insulation strengthKV/mm1918181720Dielectric constant(1Mhz)(E)9.79.59.52928 Why choose us?We have in-housing comprehensive manufacturing types of equipment, including forming, sintering, CNC machining, precision grinding, laser cutting, and so on, it helps us to control the quality very well. Also, it greatly benefits cost control.The state-of-the-art manufacturing equipmentRigorous Quality-control SystemRemark:We have the complete quality-control system per ISO9001, including IQC, IPQC, QA, and OQC process.Typical Packaging Proposal and Transportation Methods1.
