Outstanding wear resistance, over 276 times in comparison with traditional stainless steel3. Great mechanical properties, offers diamond-like hardness to be HRA85 4. Exceptional corrosion resistance, it can withstand various strong acids and alkalis, like HCL, H2SO45. Extraordinary electrical insulation, is always used in various high-voltage, high-current application6. High-precision dimensions with ideal fitting relationshipThe Description of Alumina Ceramic TubesAlumina(Aluminum Oxide, Al2O3) is the most extensively used advanced ceramic material due to its outstanding property characteristics and cost-effective advantage. As the purity increases, both wear resistance and corrosion resistance also increase, so alumina is grouped based on purity levels, including 75% alumina, 85% alumina, 90% alumina, 95% alumina, 99% alumina, 99.5% alumina, 99.8% alumina, 99.9% alumina.Alumina ceramic tubes are generally used as a standard protection part, so our facility has many selections of stocks. Our vast, readily available inventory allows us to immediately supply our customers' ceramic tube needs, even for hard-to-find or specialty products. Aluminas are used in various general-purpose applications, and their grade is chosen based on the application environment. Additionally, different purity alumina can be formulated in our factory if needed for more demand applications.Products categoryRemark:We are dealing with a wide range of advanced ceramic tubes in different raw materials, mainly including alumina, zirconia, silicon nitride, aluminum nitride, silicon carbide, and so on. Product ParametersTechnical Datasheet of advanced ceramic materialsGeneralPropertiesUnit99.5% Al2O399% Al2O396% Al2O3MechanicalVolume Densityg/cm 3≥3.90≥3.85≥3.65HardnessHRA170017001500Porosity%000Compressive StrengthMpa≥2240≥2240≥2000Bending StrengthMpa≥379≥338≥320Elastic ModulusGpa370350303ThermalThermal ConductivityW/m.K302924Coefficient of ThermalExpansion1*10 -6 m/k6.5~8.06.2~8.05.0~8.0ElectricalInsulation BreakdownKV/mm191818Volume ResistivityOhm. cm>1*1014>1*1014>1*1014  Why choose us?Our advantage and strength1.
