Custom Silicon Carbide Ceramic Shaft for Pumps

Our silicon carbide shaft is made from highly purified, sub-micron silicon carbide material processed through air pressure sintering. This results in exceptional properties including high hardness (Hv2800), superior wear resistance, resistance to strong acids, alkalis, and salt corrosion, along with excellent high-temperature performance.

• Ultra-high hardness & wear resistance: Mohs hardness of 9.5 (second only to diamond), with 5x longer lifespan than metal shafts.
• High-temperature resistance: Stable performance under 1400°C with no deformation.
• Chemical corrosion resistance: Resists strong acids, alkalis, and molten metals, ideal for harsh environments.
• Lightweight & high rigidity: 1/3 the weight of steel with superior stiffness, reducing energy consumption.
• Low thermal expansion: Near-zero expansion ensures dimensional stability in precision applications.

• Chemical pumps/valves: Corrosion-resistant shafts & seals
• Semiconductor: Wafer handling robots, vacuum chamber components
• Aerospace: Turbine engine components, high-temperature bearings
• New energy: Fuel cell stacks, photovoltaic equipment

1. Superior high-temperature performance with stable mechanical properties
2. Better performance in temperature fluctuations due to lower thermal expansion
3. Improved anti-bite and anti-stuck performance
4. Can operate without lubrication in many applications
5. Excellent resistance to acid, alkali, and salt corrosion
6. Electrical insulation and anti-static properties
7. Non-magnetic properties prevent abrasive particle accumulation
