Antslab offers Alumina Tubes with 80% Al2O3. Because high-temperature processes demand reliable components, our Alumina Tubes are most apt. Laboratory and industrial furnace applications up to 1400°C uses Alumina Tubes 80% and provide desired protection against the corrosive atmosphere. Likewise, it also protects the thermocouple sensors against mechanical damages.
Following are the properties of Alumina Tubes
- The high temperature is resistant.
- Thermal shock resistant.
- Corrosion resistant.
- High thermal conductivity.
