Product Description

C799 Alumina Ceramic Insulation Tubes for Industrial Ceramic

1:Alumina Ceramic Tubes Introduction:
Alumina or aluminum oxide (Al2O3) in its various levels of purity is used more often than any other advanced ceramic material. Tigar Ceramic offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design.

2:Ceramic tube pipe advantages

  • High hardness 
  • Superior abrasion  
  • Corrosion and chemical resistance 
  • Light weight 
  • Low maintenance cost: Super wear-resistance reduce the maintenance frequency and also the maintenance cost.
  • Good fluidity : Smooth surface ensure the free flow of material without  blocking
