Ti-13Nb-13Zr

UNS R58130· TNZ

Ti-13Nb-13Zr is a near-beta titanium alloy composed primarily of titanium with balanced additions of niobium and zirconium, designed to achieve low elastic modulus while maintaining strength and biocompatibility. It is primarily used in orthopedic implants and dental applications where reducing the stiffness mismatch between implant and bone is critical to prevent stress shielding and promote long-term integration. This alloy is notable for combining β-stabilizing elements (Nb, Zr) that lower the Young's modulus compared to conventional titanium alloys, making it attractive for load-bearing implants that require both mechanical reliability and biological acceptance without the cytotoxicity concerns of vanadium-containing alternatives.

Quality & Standards

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
