Alumina ceramic Ring (Aluminum Oxide or Al2O3) is an excellent electrical insulator and one of the most widely used advanced ceramic materials. In addition, it is extremely resistant to wear and corrosion and is an industrial ceramic that can only be formed by diamond grinding. The melting point is very high at 2,072°C, and it is very hard. Alumina components can be widely used in many fields. Eg. electronics, pump components, and automotive sensors, industrial engineering, etc. INNOVACERA Alumina includes many grades: 95% Alumina, 99% Alumina, 99.5% Alumina and 99.9% Alumina. They can fulfill customers’different demands. The dimension ranges from 1mm to 500mm. Properties: 1. Good electrical insulation 2. Moderate thermal conductivity 3. High corrosion and wear resistance 4. Good gliding properties 5. High mechanical strength 6. High compressive strength 7. High hardness
