Alumina Ceramic Insulator 99% Alumina Tube Ceramic Sleeve

About Alumina Tubes

Alumina 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.
