Product Specification

High-Performance Zirconia Ceramic Fasteners For Extreme Environments

Product Introduction
This product is a high-tech fastener made from high-purity zirconia (ZrO₂) ceramic material through advanced powder metallurgy and precision machining processes. It offers unparalleled high strength, high-temperature resistance, corrosion resistance, and excellent insulation properties, specifically designed to address the failure of metal fasteners in extreme working conditions. With its precise structure, it is often used as screws, nuts, bolts, etc., and widely applied in high-end industries such as semiconductors, aerospace, chemical engineering, and medical devices. It is an ideal solution for achieving reliable connections and long-term stable operation in precision machinery under harsh conditions.

Core Advantages

• Exceptional High-Temperature Resistance: Withstands up to 1500°C for extended periods without oxidation or creep, far exceeding the performance of most metal alloys.

• Superior Corrosion Resistance: Highly inert to most acids, alkalis, salts, and organic solvents, making it perfect for highly corrosive environments and significantly outperforming stainless steel in lifespan.

• High Strength and Hardness: High flexural strength, Vickers hardness, and wear resistance, enabling it to withstand significant mechanical stress.

• Electrical Insulation and Non-Magnetic Properties: Excellent insulation and non-magnetic characteristics, suitable for high-purity or electromagnetically sensitive environments (e.g., MRI equipment, semiconductor furnace tubes).

• Low Thermal Conductivity: Acts as an effective thermal insulator, reducing heat bridge effects.

Process Flow
Raw material preparation (high-purity ZrO₂ powder) → Isostatic pressing → Sintering (high-temperature precision sintering) → CNC precision grinding → Non-destructive testing (flaw detection) → Full dimensional inspection → Cleaning and packaging.

Usage Instructions

1. Installation: Use appropriate torque tools to avoid stress concentration caused by excessive force. Plastic or nylon sleeves are recommended to prevent damage to the ceramic surface threads during installation.

2. Matching: Use with matching zirconia nuts or corrosion-resistant metal internal threads to ensure clean and debris-free threads.

3. Precautions: Avoid exposure to sharp impact loads. Ceramic materials have lower toughness than metals, and severe impacts may cause brittle fracture. Do not use in environments involving hydrofluoric acid (HF).

FAQ

1. Q: Will zirconia ceramic fasteners rust?
   A: Absolutely not. Their corrosion resistance far exceeds that of any stainless steel, making them the ultimate solution for corrosion-related challenges.

2. Q: How do they differ from alumina ceramic fasteners?
   A: Zirconia offers significantly better mechanical properties (especially strength and toughness) than alumina, making it more suitable for high-stress connection scenarios.

3. Q: Can non-standard sizes and shapes be customized?
   A: Yes. We support customized production and machining based on customer drawings.
