Product Description Product DescriptionAlumina ceramic components Alumina ceramic (Aluminum Oxide or Al2O3) is an excellent electrical insulator and one of the most widely used advanced ceramic materials. Additionally, it is extremely resistant to wear and corrosion. Alumina components are used in a wide range of applications such as electronics, pump components and automotive sensors. Process of production:uniaxial (die) pressing, isostatic pressing, injection molding, extrusion and slip casting ect. Properties:* Good electrical insulation* High mechanical strength* Excellent wear resistance* Excellent corrosion resistance* Low dielectric constant Applicatons: * Special environment and electronic substrates* Pump seals and other components* Wear resistant inserts* Insulating washers or bushings* Semiconductor components* Aerospace components* Automotive sensors* Electrical or electronic insulators Material data AL2O3%6075808592959999.7Bulk Density (g/cm3)3.03.13.33.43.63.73.813.91Flexural strength (MPa)205280215.7230312304340370Linear expansion coefficient (×10-6/C)(25-800C)7.17.67.67.67.57.37.67.6Thermal conductivity [w/(m.R)]1617171718203435Dielectric strength (KV/mm)1010101010101010Volume resistivity (Ω.cm) 20C>1014>1014>10 14>1014>1014>1014>1014>1014300C>1013>1013>10 13>1013>1013>1012>1010>1010Max C13501100130013501500160017001800Moh's hardness7.57.57.57.58.58.899Refractoriness18001700180018501920200020302040 Company ProfileWay of shippingOur AdvantagesFAQQ1: How can know your quality?We can send you samples or sample material for you to check or test.Let our physical samples speak loudly.Q2:Are these samples free of charge?Some standard small samples are free.If same as your requirements,we will just charge for mould to support.Q3:If products are not to requirement,how can you do?We will try our best to solove.Meeting your requirement is our mission.Q4:What's the lead time?Normally,for standard items,will ship within 1-10 days.For mass production order,we will finish within 30 working days after we receive payment.Q5:Payment terms:We can negotiate.
