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.
