Product Description Technical ceramics are favoured in a wide range of electronics and engineering applications for their chemical and mechanical properties. Compared to metals, they are stronger in compression, especially at higher temperatures. Ceramics have a good thermal stability (i.e. a low coefficient of thermal expansion) and good thermal and electrical resistance. They are also hard, and have excellent dimensional stability. Al2O3 Properties: Excellent electrical insulation Relatively low strength and fracture toughness Resistance to wear and corrosive Excellent thermal stability Resistance to high temperatures High electrical resistivity Good chemical stability High corrosion resistance
