Zirconia Ceramic Needle is a revolutionary tool in the field of precision industry and high-end medical treatment. Compared with traditional metal or polymer needles, its core advantage lies in the breakthrough performance of the material itself. Zirconia (ZrO₂) ceramics can maintain the sharpness and dimensional accuracy of the needle tip for a long time with its ultra-high hardness (Mohs hardness ≥8.5) and wear resistance close to diamond, avoiding the wear and deformation problems that metal needles are prone to. Its biological inertness and excellent chemical stability ensure zero precipitation and no pollution when in contact with corrosive solvents or biological fluids, perfectly solving the risk of ion migration of metal needles. In addition, the fracture toughness of zirconia ceramic needles far exceeds that of ordinary ceramics (bending strength ≥1000MPa), and its bending resistance in precision minimally invasive operations is significantly better than that of glass or quartz needles. Empowered by material technology, zirconia ceramic needles provide an irreplaceable solution for high-cleanliness, high-precision and long-life application scenarios.
