Alumina, also known as Aluminum Oxide, is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications. Once fired and sintered, it can only be machined using diamond-grinding methods. It features high hardness and wear resistance, low erosion levels, high temperature resistance, corrosion resistance, and bioinertness.Additionally, it can be highly polished, making it useful for a wide range of applications. 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
