    Alumina Ceramic Machining and Grinding, Material Properties Data

    At 1000°C (orange heat) alumina ceramics retain approximately 50% of their room-temperature tensile strength, while most metals will not support their own weight at this temperature. Metals are weakened by oxidation reactions at high temperatures, but when returned to ambient temperature the mechanical strength properties of ceramics are ...
