Silicon Carbide Balls

What Are Silicon Carbide Balls?

Silicon Carbide Balls are ceramic spheres made from silicon carbide (SiC), a material renowned for its superior strength and thermal stability. These balls perform reliably under extreme mechanical stress, chemical exposure, and elevated temperatures.

Key Features

• Exceptional hardness — second only to diamond, making them highly wear-resistant.
• Excellent corrosion resistance — suitable for acids, alkalis, and seawater.
• Thermal stability — withstands temperatures up to 1600°C (2900°F).
• Low friction coefficient — reduces wear and energy loss in rotating parts.
• Oxidation resistance — maintains integrity even in high-oxygen environments.

Manufacturing and Quality

These balls are made through precision processes including sintering and fine grinding, ensuring tight dimensional tolerances and consistent performance.

• High dimensional accuracy — typically exceeds ISO Grade 3 standards.
• Smooth surface finish — Ra 0.17–0.25 µin for reduced friction and extended bearing life.
• Available sizes — from 0.5 mm to 50 mm, with custom options available.

Applications

• Silicon Carbide Balls in medical devices — used for their strength and biocompatibility.
• Aerospace and aviation — high temperature and corrosion resistance for turbines and actuators.
• Automotive components — ideal for hybrid and electric vehicles, especially in high-load areas.
• Industrial pumps and valves — operate efficiently in harsh chemical environments.
• Energy and power systems — suitable for high-stress conditions in nuclear or thermal power generation.

Conclusion

Silicon Carbide Balls are an optimal choice for applications where traditional steel or plastic components fall short. Their unmatched hardness, thermal resistance, and chemical durability offer a long-term solution for critical, high-performance systems.
