Description
Alumina Ceramic Sealing Ring
Properties of alumina ceramic sealing ring:
1.High hardness (15 to 19 GPa)
2.Moderate thermal conductivity (20 to 30 W/mK)
3.High corrosion and wear resistance
The ceramic rings are used in a number of applications as an alternative to industrial diamond, as they are far more affordable to produce.

Alumina ceramics are the industrial ceramic oxides of Aluminum which are used in many different industries for their hardness and resistance to abrasion, as well as their superior heat resistance.
Surface roughness of the ceramic ring:
The surface processing of ceramic ring can achieve very high precision: the inner hole surface can reach 0.005mm, the outer hole surface can reach 0.001mm, and the mirror polishing can reach Ra0.1.
Finishing ability
- The maximum height is 600mm
- The maximum length is 2500 mm
- The maximum CNC length is 1200 mm
