Alumina ceramic:

 

We are make 99.7% Al2O3 tubes, which max working temperature is 1800ºC and 95% Al2O3 tubes,
which max working temperature is 1500ºC

According to different usage, our tubes are widely used for furnace tube, thermocouple protection tube,
thermocouple insulator and other applications.

 

 

Application:

 

1. Good insulation tube

2. Inner liner tube and heating tube in electric furnace

3. Use for the Vacuum environment
