Silicon Carbide (SiC) Ring Advantages

  • Excellent Hardness and Wear Resistance
    Silicon Carbide (SiC) has a very high hardness (Vickers Hardness of 2100 HV1), which allows the ceramic ring to exhibit excellent wear resistance and durability when handling high-hardness materials.
  • High compressive strength
    Extremely high compressive strength (2600 Mpa), capable of withstanding heavy loads and suitable for high-pressure environments.
  • Low coefficient of friction and thermal stability
    A low coefficient of friction and high thermal conductivity (100 W/mk) ensure efficiency and thermal stability at high speeds, while minimizing shape changes caused by thermal expansion (Thermal Expansion Coefficient of 4x10-6 K-1).
  • Thermal Shock Stability
    Excellent thermal shock resistance (Thermal Shock Resistance of 400°C) enables stable performance in environments with rapid temperature changes.
  • Chemical Stability
    The chemical stability of Silicon Carbide materials enables them to be used in corrosive environments and is not easily affected by chemicals.
