customized high precision refractory ceramic sandblasting nozzles
for tig welding
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.
