Alumina Tube Description
alumina tube Alumina tude is made of aluminium oxide (Al2O3)
ceramic. Alumina as a fine ceramic material is widely used in a lot
of industries. Aluminum oxide tubes has superb performances in
electrical insulation, high chemical resistance and low thermal
expansion and these ceramic tubes are widely used in industrial
ovens and machines. High purity alumina materials are excellent for
making alumina components for CVD, ion implants, photolithography,
and semiconductor manufacturing.
In traditional industries, alumina ceramic tubes are ideal for
products such as injector tubes and insulators. Alumina tubes are
also widely used as protector for high temperature thermal couples.
