Q: How much weight savings does Titanium Derailleur Pulley offer versus steel or aluminum? ▼
Titanium Derailleur Pulley fabricated from Grade 5 Ti-6Al-4V provides a 40-45% weight reduction versus 4130 chromoly steel (4.43 vs 7.85 g/cm³) at the same strength. Compared to 6061-T6 aluminum, titanium's 3× higher yield strength (830 vs 275 MPa) allows 50-60% thinner walls, resulting in a net weight comparable to aluminum with 4× better fatigue life — critical for rear derailleur guide.
Q: What is the typical lead time for Titanium Derailleur Pulley orders? ▼
Standard lead time for Titanium Derailleur Pulley 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 Derailleur Pulley? ▼
Each Titanium Derailleur Pulley 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 rear derailleur guide.
