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.

Application of Ceramic Shaft
Pump Equipment
Ceramic shafts are corrosion-resistant and rust-free, suitable for media environments such as acid and alkali solutions, seawater, and pure water. They can be used in water pumps, chemical pumps, metering pumps, peristaltic pumps, ceramic impeller shafts, etc. They are not prone to wear during long-term operation and extend the service life of the pump.
Electric Motors
Ceramic shafts are lightweight and reduce moment of inertia, contributing to energy savings and efficient operation. Their excellent insulation properties prevent electrical corrosion on metal motor shafts caused by current leakage, making them commonly used in small motors, stepper motors, and brushless motors.
Home Appliances
In aquarium equipment (such as fish tank pumps, filters, and ceramic impeller shafts), ceramic shafts are quiet, free of magnetic interference, and corrosion-resistant. In small household appliances (such as soymilk makers, juicers, water purifiers, and air conditioning compressors), ceramic shafts can reduce noise and wear, improving durability.
Medical Devices
Ceramic shafts are used in medical pumps and testing equipment because of their good biocompatibility and strong chemical resistance to avoid contamination.
Cars and Transportation
Ceramic shafts can be used in fuel pump shafts, turbocharger components, hybrid and electric vehicle motor shafts, etc. The ceramic material can significantly improve high temperature resistance and friction, and enhance reliability.
Industrial Machinery
Ceramic shafts operate stably in highly clean and high-temperature environments, and can avoid metal corrosion caused by magnetic fields and chemical media. They can be used in precision machinery, semiconductor equipment, textile machinery, magnetic pumps, and vacuum equipment.
