alumina Gas welding torch nozzle

الوصف

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.
