Alumina Ceramic Insulator 99% Alumina Tube Ceramic Sleeve
About Alumina TubesAlumina Ceramic tubes have exceptional hardness and strength, resistance to chemical attack and wear, low dielectric loss and excellent electrical insulation properties. Additionally, Alumina can be metallized for brazing to other metals, highly polished, and comes in a variety of purities depending on it use. Due to these outstanding properties ceramic Alumina tubes are used in a wide range of industrial and advanced applications.
For more information on Alumina please refer to our General Alumina Page.
Additionally, we supply extruded ceramic Alumina tubes and pipes offered in both stock sizes and custom sizes, designed and machined to precise customer specifications. If you would like to buy Alumina Tubes or have any questions, please contact us and one of our experts will be happy to assist you.
Alumina ceramic is kind of structural ceramics, with insulation resistance, voltage resistance, high strength, good thermal conductivity, dielectric loss, stable electrical performance characteristics. Used in electronic ceramic substrates, ceramic electrical insulation, vacuum devices, devices porcelain, spark plugs and other products. We can make the part by hot injection pressing, dry pressing, isostatic pressing and extrusion productive technology etc.
