TB13 Titanium Wire Introduction
TB13 titanium wire is a high-performance β titanium alloy featuring exceptional superelasticity, low elastic modulus, superior springback resilience and excellent cold formability. It is commonly utilized for eyewear frames, medical hardware and precision elastic components.
As a China-originated alloy, TB13 has no ASTM counterpart. It is internationally designated Ti-4Al-22V for global procurement and technical records. Grade 19 (Ti-15-3) and β‑C are the most comparable engineering alternatives.
