Titanium Spoke Nipple is a lightweight hexagonal spoke nipple component engineered for Hexagonal spoke nipple for rim interface. Forged and CNC machined from Grade 5 Ti-6Al-4V, it achieves 40-45% weight savings versus steel while maintaining the fatigue life required for demanding cycling applications. Threaded interfaces are designed to prevent galling in outdoor environments.

Q: Does Titanium Spoke Nipple require special assembly or anti-seize? ▼
Yes. Titanium-to-titanium threaded interfaces on Titanium Spoke Nipple are susceptible to galling (cold welding) during assembly. Application of MoS₂ or copper-based anti-seize compound to all threaded contact surfaces is mandatory. Lubricated installation torque values are typically 15-20% lower than dry values. Thread engagement should not exceed 3× thread diameter.
Q: What is the typical lead time for Titanium Spoke Nipple orders? ▼
Standard lead time for Titanium Spoke Nipple is 15-25 business days depending on quantity and complexity. Rush orders (3-5 working days) are available for prototype evaluation. Sample evaluation (1-5 units) can be expedited to 5-7 business days. Volume pricing is available for production quantities above 100 units.
Q: What material certifications are provided with Titanium Spoke Nipple? ▼
Each Titanium Spoke Nipple shipment includes EN 10204 Type 3.1 mill test certificate with chemical analysis, mechanical properties, and heat identification. Dimensional inspection reports and Certificate of Conformance (CoC) are standard. First Article Inspection Reports (FAIR) per AS9102 are available on request for hexagonal spoke nipple.
