Corrosion resistance and biocompatibility
Implant-grade niobium rods (purity ≥99.95%) are corrosion-resistant in body fluids and have better biocompatibility than titanium. They are used in dental implants and bone fixation devices.
Comparative data: The corrosion rate of niobium in simulated body fluids (0.01 mm/year) is much lower than that of titanium (0.03 mm/year).
Mechanical properties
Tensile strength: Pure niobium rods are about 150 MPa, and niobium alloys (such as Nb-1Zr) can reach more than 500 MPa.
Hardness: Brinell hardness is about 60-80 HB, and the surface can be hardened to 120 HB after processing.
