Wear Resistance Alumina Ceramic Tubes With Good Insulation Performance

 

 

Ceramic furnace tubes, thermocouple protection tubes and insulating rods produced by Mingrui are made of alumina ceramic (Al2O3 > 99%). Alumina ceramic possesses a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion. The max. using termperature of these tubes & rods can be up to 1800 °C. They are an excellent choice in furnace and temperature measurement whenever safety and stability are required.

 

The size of the high temperature ceramic tubes & rods can be customized according to customer's requirement:

 

 

 

Specification:
 

*Good thermal conductivity
*Good strength and hardness
*Good resistance to wear and corrosion
*Temperature resistance up to 1800°C
