High purity alumina rod

详情

 Alumina in its various degrees of purity is a versatile material that offers a combination of good mechanical and electrical properties and probably the most important oxide ceramic for widely varying technical applications. Depending on the alumina purity, particular the purity ranging from *5% to >*9.9%, 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 seal rings, laser tubes, electrical insulators, threadguides, refractory devices, electronic substrates, thermocouple tubes, grinding media and wear components. 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 metallising and brazing techniques.
