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 acid and alkali, like HCL, H2SO45. Extraordinary electrical insulation, it 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 with the purity increases, both wear resistance and corrosion resistance also increases, so alumina are grouped together 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 kind of standard protection part, so our facility has many selections of stocks. Our vast, readily available inventory allows us to supply our customer's ceramic tube needs immediately, even for hard-to-find or specialty products. Aluminas are used in a variety of 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 applicationsProducts categoryRemark:We are dealing with a variety of advanced ceramic tubes in a selection of 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% Al2O3SteatiteYTPZZrO2SiCMechanicalVolume Densityg/cm 3≥3.90≥3.85≥3.65≥2.70≥6.0≥3.13HardnessHRA17001700150080013002500Porosity%000000Compressive StrengthMpa≥2240≥2240≥2000≥551≥1990≥ 2200Bending StrengthMpa≥379≥338≥320≥190≥1200≥400Elastic ModulusGpa370350303110210400ThermalThermal ConductivityW/m.K3029242.53120~150Coefficient of ThermalExpansion1*10 -6 m/k6.5~8.06.2~8.05.0~8.07.7~8.08.0~9.54ElectricalInsulation BreakdownKV/mm1918181017-Volume ResistivityOhm.Cm>1*1014>1*1014>1*1014>1*1013>1*10115*10 6  Why choose us?Our advantage and strength1.
