Product Description

Dark Gray Flanged Silicon Nitride Ceramic Ring: High-Strength Wear-Resistant Precision Annular Component

Product Introduction
This product is a dark gray annular ceramic component manufactured from high-purity silicon nitride material, innovatively designed with a flanged structure that combines excellent mechanical strength with precise dimensional control. Through advanced sintering technology and precision machining, the product achieves mirror-level surface smoothness, demonstrating the outstanding comprehensive properties of silicon nitride material. This ceramic ring not only inherits the inherent high strength and high toughness characteristics of silicon nitride but also achieves multi-functional integration through unique structural design, making it an ideal key component solution for high-speed and high-pressure operating conditions.

Core Advantages

  • Exceptional Mechanical Properties: Flexural strength ≥800MPa, fracture toughness ≥6.5MPa·m¹/²

  • Excellent Wear Resistance: Hardness up to HRA 90-93, wear rate lower than 10⁻⁷mm³/N·m

  • Outstanding Temperature Resistance: Maintains stable performance at high temperatures up to 1200°C

  • Lightweight Design: Density only 3.2g/cm³, approximately 60% lighter than steel

  • Superior Corrosion Resistance: Resistant to acids, alkalis, and oxidation, suitable for harsh environments
