Durox® Alumina Ceramics Offer High Strength And Thermal Stability
Materion’s Durox family of alumina (Al2O3) technical ceramics provides a cost-effective solution for applications requiring high thermal and dimensional stability and low thermal expansion within very tight tolerances. The high-purity alumina ceramics come in a range of shapes and purities to match your advanced ceramics needs.
DUROX ALUMINA TECHNICAL CERAMICS PROPERTIES AND PURITY
- Etching resistance
- High stiffness-to-weight ratio
- High temperature stability
- Low thermal expansion
- High dielectric strength
- Corrosion resistance
- Optimum wear resistance
The hardness of our high purity alumina is only surpassed by diamonds and alumina is only a fraction of the cost. Manufacturers can rely on alumina ceramic material when used in parts and components subjected to high temperature environments.
We offer two grades of Durox ceramics:
- Durox 98 ceramic is 97.6% pure Al2O3 and is the most affordable alumina ceramic option for ceramic components.
- Durox AL ceramic is 99.8% pure, offers higher tensile strength, dielectric strength and thermal conductivity.

APPLICATIONS AND FORMS OF DUROX CERAMICS
Durox ceramics are ideal for applications such as:
- Photonics/ lasers
- Semiconductor manufacturing, including heat sinks, substrates, laser tubing and resistor cores
We can produce Durox alumina ceramics in several standard and custom shapes. These highly engineered materials can be formed through dry-pressing, iso-pressing and extrusion. For small ceramic parts, dry-pressed Durox alumina can be formed into disks, heat sinks, plates, transistor outline (TO) packages, washers, and small resistor cores. For larger shapes, cold isostatic pressed Durox ceramics can be made into tubes, rods, blocks and ceramic crucibles.
