Ti-13Nb-13Zr wire is a near β alloy formulated at the beginning of the 1990s to be used in orthopedic applications due to its low Young’s MODULUS (40-80 GPa) and its non-toxic composition. The main advantage of the Ti-13Nb-13Zr alloy, compared to other titanium alloys, such as Ti-6Al-4V and Ti-6Al-7Nb, widely used as biomaterials, is its low elasticity modulus, closer to that of bone, and the absence of aluminum and vanadium, which have been reported to cause long-term adverse effects. It presents tensile values of approximately 1300 MPa and superior corrosion resistance when compared to Ti-6Al-4V and Ti-6Al-7Nb.
