OMEGA Engineering, Inc. Datasheets for Aluminum Oxide and Alumina Ceramics

Aluminum oxide and alumina ceramics have excellent wear characteristics, chemical resistance, compressive strength, high-temperature properties, and dielectric strength. They are used widely because of their versatility and low cost. Their main drawback is its relatively poor thermal-shock resistance due to higher coefficients of thermal expansion and lower thermal conductivity (compared to other pure ceramic materials).
