Alumina ceramics, Al2o3 ceramics, 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.
The products are made of high purity Zirconia ceramics (Zro₂) and Alumina Ceramics (Al₂O₃) material, which have
advanced and excellent performances, fabulously popular .
