Product Description Product Description Alumina ceramic parts are a type of ceramic material mainly composed of high-purity alumina (Al2O3), which has extremely high hardness, wear resistance, high temperature resistance, and chemical stability. It is widely used in multiple industrial fields and is currently the largest and most widely used industrial ceramic material in terms of production volume.Technical SpecificationItemAl2O3≥99%Al2O3≥95%ZrO2≥94% Physical propertiesDensity3.853.65.9Water Absorption %000Sintering temperature °C169016701650 Quality characteristicsHardness HV170016001400Flexural strength 4pt>3500>2900>11000Compressive strength /cm2300002500025000 ThermodynamicpropertiesMaximum service temperature °C150014001600Coefficient of thermal expansion 8 7.81010-6/°C0-1000°CHeat shock resistance (°C)200220350Thermal conductivity W/m.k31223 ElectricalcharacteristicsVolume resistivity Ω.cm>10^12>10^12>10^12Breaking strength of insulation KT/m181615Dielectric constant 1MHZ(E)9.2-10.59.0-1012.5Length(mm)Width(mm)Height(mm)Wall thickness(mm)Capacity(cc)6-20030-15015-190>25-5000 Our Advantages1. High hardness and wear resistance Hardness:The Mohs hardness of alumina ceramics is as high as level 9, second only to diamond. Wear resistance: Its wear resistance is 266 times that of manganese steel and 171.5 times that of high chromium cast iron.2. High temperature resistance and thermal stabilityHigh temperature resistance: The melting point of alumina ceramics is as high as 2050 oC, and it can maintain stable performance at a high temperature of 2000 oC. Thermal stability: It has a low coefficient of thermal expansion and can maintain structural stability under extreme temperature changes.3. Lightweight design Density:The density of alumina ceramics is only 3.6-3.8g/cm 3, which is over 50% lighter than steel. For example, using alumina ceramic components in airplanes can reduce weight by 30% and significantly improve fuel efficiency.4. Corrosion resistance and insulation properties Corrosion resistance:Excellent resistance to strong acids, alkalis, and salt media, suitable for chemical reactors, anti-corrosion valves, etc. Insulation: With a resistivity of ≥ 1 × 10 ^14Ω· cm, it is the preferred material for high-frequency electronic device substrates.5. High cost-effectiveness Cost effectiveness:Its long lifespan and low maintenance characteristics significantly dilute long-term costs.6. Customized processing Precision machining:Through processes such as dry pressing, injection molding, and 3D printing, complex shaped precision components can be made to meet the needs of high-end fields such as semiconductors and medical equipment. Quick response customization: Enterprises can customize ceramic parts according to equipment parameters, reducing adaptation costs.7. Environmental Protection and Sustainability Low carbon production:The raw materials for alumina ceramics (alumina powder) are widely available, and the energy consumption of sintering process is lower than that of metal smelting. Recycling: Waste ceramics can be crushed and recycled as raw materials to avoid pollution risks caused by metal material wasteApplications:Mechanical and structural ceramics: used for bearings, sliders, seals, etc., to reduce failures and downtime.Chemical and high-temperature industries: used as refractory materials, insulation materials, chemical reactor liners, and pipeline fittings.Electronics/Power: Used for electronic substrates, insulation sleeves, etc., providing high insulation performance.Medical: Used for artificial joints, dental implants, etc., with excellent biocompatibility.Aerospace: Used for engine components, turbine blades, etc., to enhance the reliability of power systemsSemiconductor production: growing crystals or depositing thin films on thin substrates.Packaging & ShippingShipping and PackingPackage TypeContainer Load CapacityDelivery timeQualityInsurancePayment Terms20 GP40 GPTon bag20 m340 m3Within 7-14 daysChinese National Standard; Offer quality assurance as request.T/T, L/C, Paypal, West UnionPlastic bag20 m340 m3Paper box20 m340 m3Wooden box20 m340 m3Company ProfilePingxiang Bestn Chemical Packing Co., Ltd was established in 2007, It is a professional manufacturer and exporter that has more than 10 years experience in Chemical Packing.
