Zirconia Ceramic Precision Sleeve: High-Temperature Resistant, Insulating, And Wear-Resistant Solution

Zirconia Ceramic Precision Sleeve: High-Temperature Resistant, Insulating, And Wear-Resistant Solution

Product Introduction
This product is a cylindrical structural component with holes made from high-purity zirconia (ZrO₂) ceramic material, manufactured through advanced powder metallurgy and precision machining processes. It exhibits excellent mechanical strength, wear resistance, and chemical stability, making it an ideal choice for insulating sleeves, bearing rings, and wear-resistant connectors in precision machinery. Its unique combination of properties addresses the performance limitations of metal materials in insulating, wear-resistant, and corrosion-resistant environments.

Core Advantages

• Exceptional Wear Resistance: Vickers hardness ≥1250, wear resistance is 10 times that of ordinary steel

• Excellent Insulation Properties: Volume resistivity >10¹⁰ Ω·cm, maintains stable insulation under high temperature and high pressure conditions

• Superior Corrosion Resistance: Resistant to acid and alkali corrosion, suitable for chemical, medical and other corrosive environments

• High Mechanical Strength: Flexural strength ≥1000 MPa, can withstand high load conditions

• Precision Dimensional Stability: Thermal expansion coefficient close to metal, enabling precise matching with metal components
