Alumina Tubes and Rods are Used in a Wide Variety of Applications
Alumina is the most widely used technical ceramic and is the material of choice in about 80% of engineering applications due to its excellent combination of properties. Fired at over 1600°C (2910°F) to give a fully dense ceramic, Alumina exhibits high mechanical strength and stiffness that is retained even at elevated temperatures.
Alumina tubes and rods are found across numerous user industries as a cost-effective yet high-performance solution. The combination of key properties makes them a go-to product in many instances:
- Thermally stable – Alumina can be used in both oxidizing and reducing atmospheres up to 1600°C (2910°F) and in vacuum furnaces up to 1750°C (3180°F).
- Fully dense – Alumina provides a non-permeable tube that protects from contamination and can be used to create a gas-tight assembly.
- High chemical resistance – Alumina is chemically inert and not corroded by water or steam. It offers good resistance to corrosive substances such as strong acids or alkalis, even at elevated temperatures.
- Electrical insulation – Alumina is also widely used as an electrically insulating material. It can be used for insulators operating at elevated temperatures (e.g. furnace lead-in tubes, fuel-cells)
