Product Overview
TB13 titanium wire is a metastable beta titanium alloy with a nominal composition of Ti-4Al-22V. Its high beta-stabilizer content supports strong cold-workability, elastic recovery and precision forming for demanding wire components.
The alloy is especially suited to spectacle-frame wire and other parts that require repeated forming, resilience and corrosion resistance. It can be supplied in solution-treated condition to YS/T 1077-2015, with other conditions or specifications evaluated against the purchase requirement.
Each quotation is reviewed against the requested diameter, tolerance, temper, surface, quantity and inspection-document needs before production is confirmed.

Features & Advantages
- TB13 / Ti-4Al-22V: Beta alloy wire developed for formability, resilience and precision wire applications.
- Cold workability: Suitable for drawing, bending and complex frame-forming routes.
- Elastic recovery: Supports flexible components that must recover after controlled deflection.
- Corrosion resistance: Titanium-based performance for perspiration and everyday environments.
- Lightweight design: Lower density than common steels for comfortable finished components.
- Order-specific control: Diameter, temper, surface and documents are reviewed before quotation.
Performance Solutions
1. Problem: High-strength wire may crack during tight-radius bending.
Solution: TB13’s beta-alloy structure supports strong cold-workability for controlled forming routes.
2. Problem: Thin components can remain permanently distorted.
Solution: TB13 provides useful elastic recovery for spectacle frames and resilient precision parts.
3. Problem: Steel wire can add unnecessary mass to wearable products.
Solution: Titanium alloy construction supports lighter component design.
4. Problem: Diameter alone is not enough to confirm suitability.
Solution: We review condition, tolerance, surface, quantity and test-document requirements before production.
Applications
-
1. Spectacle frames: Rims, bridges, temples and formed wire components requiring resilience.
2. Precision springs: Small elastic parts and clips developed through controlled forming.
3. Consumer hardware: Lightweight wire details for daily-use and wearable products.
4. Electronic components: Precision wire parts where low mass and corrosion resistance are valued.
5. Custom formed parts: Industrial wire components subject to drawing, forming and qualification review.
