Alumina ceramics have high flexural strength and compressive strength, and can maintain good stability at room temperature or high temperature. It can be made into mechanical parts such as cutters, ball valves, bearings, etc.
Alumina ceramic is a very hard material, its Mohs hardness can reach 9, second only to diamond. It has excellent wear resistance and scratch resistance, and can be used in the manufacture of cutting tools, grinding wheels, wire drawing dies, etc.
High temperature resistance: Alumina ceramics have a high melting point (2050°C) and good oxidation resistance, and can be used in a vacuum environment or inert gas up to 2000°C. It is very resistant to many metallic and non-metallic materials.
Alumina ceramics have high resistivity and dielectric strength, and can maintain good electrical insulation performance under low or high frequency conditions. It can be made into electronic components such as substrates, sockets, and spark plugs.
Corrosion resistance: Alumina ceramics have excellent chemical stability and will not react or dissolve to many acid-base salt solutions and organic solvents. It is also resistant to attack by substances such as glass and scum.
