Material Introduction

Our alumina ceramics are made from synthetic raw materials with aluminum concentrations of more than 80% Al2O3 to 99.7%Al2O3. The material composition is selected according to the technical and economical requirements. In this way, high hardnessand strength or good wear resistance in various tribological composition can be achieved. Aluminum oxide is extremely thermallystable and resistant against corrosion at very high temperatures.
