SIC Silicon Carbide Ceramic Sealing Ring Features.
1. High Temperature resistance, SiC can withstand 1200ºC, SSiC can withstand 1500ºC.2. High strength and excellent hardness.
3. Good Corrosion and Oxidization resistance.
4. Tight tolerance and good surface roughness.
We supply high quality precision silicon carbide ceramic rings according to your blueprint.
We can provide all SiC, SSIC and SSIC+C sealing rings under a diameter of 700mm. including special shaped rings. We can supply products according to your blueprint with following standards applied.
- Tolerance, the best tolerance we can control is +/-0.02mm.
- Surface Roughness, we can polish the surface to Ra0.1um at most.
