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

1. The high temperature is resistant.
2. Thermal shock resistant.
3. Corrosion resistant.
4. High thermal conductivity.
