Description
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 at elevated temperature. For more information about Alumina Tubes and technical ceramics, enquire or speak to IPS Ceramics.
