Introduction of Silicon Carbide Fine Balls

Silicon Carbide Fine Balls are high-performance ceramic spheres made from high-purity Silicon Carbide (SiC) with excellent hardness, wear resistance, and chemical stability. Silicon carbide is an advanced engineering ceramic material known for its high hardness, high thermal conductivity, and thermal shock resistance. Widely used in precision grinding, bearings, valves, and high-temperature industries, Silicon Carbide Fine Balls are efficient, durable, and reliable engineering components.

Features of Silicon Carbide Fine Balls

High hardness and wear resistance: The high hardness of silicon carbide, second only to diamond and cubic boron nitride, can effectively resist wear and prolong service life.

Excellent high-temperature resistance: able to work stably in high-temperature environments above 1600°C.

High thermal conductivity: excellent thermal conductivity, suitable for scenes requiring rapid heat dissipation.

Thermal shock resistance: able to withstand rapid temperature changes and suitable for frequent heating and cooling conditions.

Chemical Stability: Extremely resistant to acids, alkalis, and most molten metals.

Low coefficient of thermal expansion: good dimensional stability during temperature changes, reducing the risk of cracking due to thermal stress.

High mechanical strength: high compressive strength and fracture toughness, able to withstand large mechanical stresses.

Low contamination: almost no impurities are introduced during the precision grinding process, ensuring the high purity of the powder.
