Alumina is a versatile material in ceramics family that contains various degrees of purity. It provides with a good combination of both electrical and mechanical properties and this is the most important oxide ceramics for widely varying applications. Depending on the alumina purity, particular the purity ranging from *5% to >*9.7%, these aluminum oxide ceramics have variety of properties:
-Good mechanical strength 
-Good heat conductivity 
-Good fire resistance
-Good corrosion and wear resistance 
-Good sliding properties 
-Very good electric insulation
It is suitable for a wide range of applications including:
-Thread guides
-Seal rings
-Grinding media
-Wear components
-Electronic substrates 
-Thermocouple tubes
-Electrical insulators 
-Refractory devices
-Laser tubes 
It has a good strength and stiffness, very high hardness and resistance to wear. In addition it can be readily joined to metals or other ceramics using specially developed metalizing and brazing techniques.
