Customized Ceramic Shaft Material Parameters and Selection
Guide to Choosing Various Ceramic Materials!
✔️Alumina: Alumina shaft is the cheapest among many materials, with a very high cost performance. Its density is 3.7-3.92g/cm3 . You can choose 95%, 99%, 99.5%, 99.7% and other purity alumina for customization.
✔️Zirconia: The density of zirconia shaft is relatively large, exceeding 6.0g/cm3. It has stronger fracture performance than other materials, overcomes the brittleness of ceramics, and it is also self-lubricating, which is very suitable for shaft and pump applications. In addition, you can also choose TTZ, YTZP, ZDY, ZTA and other materials.
✔️Silicon nitride: Silicon nitride shafts are more expensive, but they are lighter and can be polished to a mirror finish of Ra0.05um.
✔️Silicon carbide: The density of silicon carbide shafts is similar to that of silicon nitride, and their hardness is higher than that of general ceramic materials, and their wear resistance is also better.

Ceramic Shaft vs. Metal Shaft
Ceramic shafts have excellent wear resistance and corrosion resistance, especially in some high temperature and corrosive environments.
Metal shafts have better impact and vibration resistance, but are easily corroded and worn.
Ceramic Shaft Manufacturing Process
- Raw material preparation: Select and process suitable ceramic raw materials.
- Molding: Dry pressing, injection molding, etc.
- Drying: Remove moisture after molding and wait for sintering.
- Sintering: High temperature sintering to form a hard ceramic structure.
- Post-processing: Precision machining or other processing.
