High Hardness 96% Al2O3 Alumina Ceramic Insulating Tube Pipe Sleeve¹

Product Description Product DescriptionAlumina CeramicAlumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together withhigh hardness and good wear resistance,but relatively low strength and fracture toughness.Alumina ceramic is generally white butmay also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.Features & Advantages1. High hardness.2. High heat resistance: alumina ceramic has excellentthermal stability,which means that it is widely used in areas whereresistance to high temperatures is essential.3. Good wear resistance: alumina ceramic is the material of choice for alumina wear parts.4. High electrical resistivity: alumina is an electrically insulating material.5. High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Goodchemical stability of alumina leads to high corrosion resistance.  Material85 Al2o390 Al2o395 Al2o399.7 Al2o3Al2o385%90%93%99.30%Fe2o3≤1.0≤0.5≤0.5≤0.3Desnsity:g/cm33.43.53.63.85Vickers Hardness≥8.6≥8.899Water Absorption:%≤0.2≤0.1≤0.085≤0.01Refractoriness:oC1580oC1600°oC1650oC1800oCFlexural Strength:Mpa180200240280Wear Rate(at room temperatureerosion,100 grinding)%≤3≤2.5≤1≤0.5 Company ProfilePackaging & ShippingFAQ1.
