Core Materials & Key Properties

• Main Material Options:
  • High-purity alumina (Al₂O₃ ≥99.5%): Cost-effective, good wear resistance, suitable for medium-temperature (≤1600℃) and general corrosive environments.
  • Zirconia (Y-TZP): High toughness, excellent thermal shock resistance, ideal for dynamic sealing with frequent temperature changes.
  • Silicon carbide (SiC): Superior hardness and chemical inertness, resistant to strong acids/alkalis and high-speed friction.
• Critical Performance Traits:
• Ultra-low wear rate: Hardness up to HRA 90+, minimal abrasion even in high-speed rotating or reciprocating motion.
• Strong corrosion resistance: Unaffected by most chemicals, solvents, and corrosive gases/liquids.
• Wide temperature adaptability: Operating range from -200℃ to 1800℃, maintains sealing performance under extreme temperature fluctuations.
• High dimensional precision: Tolerances up to ±0.002mm, ensuring tight fitting and leak-proof sealing.
• Non-toxic & contamination-free: Suitable for food, medical, and semiconductor industries requiring high purity.

Typical Applications

• Fluid machinery: Pumps, valves, compressors, and pipelines in chemical, petroleum, and water treatment industries.
• Automotive & aerospace: Engine cooling systems, hydraulic systems, and fuel delivery components.
• Medical equipment: Precision pumps, analytical instruments, and surgical devices (non-reactive with bodily fluids).
• Semiconductor manufacturing: High-purity gas/liquid delivery systems, vacuum furnaces (low impurity emission).
• Food & beverage: Processing equipment, beverage pumps, and dairy machinery (hygienic, easy to sterilize).

Customization & Technical Specifications

• Size range: Inner diameter 5–500mm, outer diameter 10–550mm, thickness 1–20mm (customizable).
• Surface finish: Polished (Ra ≤0.05μm) for enhanced sealing contact and reduced friction.
• Structural designs: Flat rings, O-rings, V-rings, or stepped rings (adaptable to different sealing interfaces).
• Additional options: Coated surfaces (e.g., DLC for lower friction), porous ceramic structures for self-lubrication.
