Alumina ceramics, Al2o3 ceramic, has the advantages of high melting point and boiling point, high hardness, insulation at normal temperature, and electrical conductivity at high temperature.
Alumina Ceramic tube has 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.
