Zirconia ceramic screw

Zirconia ceramic screws are special fasteners made from high-purity zirconia (ZrO ₂) through precision molding, sintering, and processing. Featuring excellent mechanical properties, chemical stability, and biocompatibility, it is suitable for extreme or special environments that traditional metal screws cannot meet.

Core product advantages

1. Excellent corrosion resistance
   Completely resistant to acid, alkali, salt spray, and organic solvent corrosion, with a lifespan of more than 5 times that of stainless steel screws, suitable for highly corrosive environments.
2. Ultra high hardness and wear resistance
   Rockwell hardness HRA ≥ 88, friction coefficient as low as 0.15, long-term use without abrasive particle shedding, protecting connecting components.
3. Insulation and non-magnetic
   Volume resistivity>10 ¹⁵Ω· cm, completely non-magnetic, does not interfere with electromagnetic fields, ideal choice for precision instruments and medical equipment.
4. Excellent biocompatibility
   Compliant with ISO 10993 biocompatibility standard, non-toxic and harmless, widely used in human implantable devices and food contact equipment.
5. High temperature and low temperature stability
   The working temperature range is -200 ℃ to+800 ℃, with a thermal expansion coefficient close to that of metals, to avoid thermal stress loosening.
6. Lightweight and high specific strength
   The density is only 6.05g/cm ³, with a higher specific strength than titanium alloy, reducing system load.
