| Alloy | Shear | vs CFRP | Notes |
|---|---|---|---|
| Titanium (Ti-6Al-4V) | 50 ksi | low | Ti/Cb (titanium-niobium), ductile |
Install tooling & training
- Tool
- Rivet gun + bucking bar (both sides)
- Special / proprietary
- Standard tooling
- Training
- Standard riveting; composite bucking needs care.
- Inspection
- Shop-head form; Hollow-End: soft bulge, no splitting.
Standard bucking; the Hollow-End variant uses a soft upset so it can be set in composite without splitting the laminate.

Strengths
- +Light Ti/Cb (~33% lighter than Monel)
- +Ductile — minimal sheet distortion
- +Corrosion-resistant, no coating
Trade-offs
- −Needs back-side access (bucking)
- −Lower shear (~50 ksi)
- −Not removable
Typical applications
- · Weight-critical riveted structure (lighter than Monel)
- · Fatigue-critical, ductile joints
- · Composite assemblies (Hollow-End soft-upset variant)
