Product Overview
Grade 5 titanium wire is the most widely used titanium alloy wire, offering high strength, good corrosion resistance, and excellent strength-to-weight ratio. It is commonly specified for aerospace, medical, and high-performance industrial components. Grade 5 wire is used for fasteners, springs, formed-wire parts, and as feedstock for joining processes where Ti-6Al-4V is required.
Chemical Composition

| Vanadium | 3.50–4.50% |
| Iron | ≤ 0.40% |
| Oxygen | ≤ 0.20% |
| Carbon | ≤ 0.08% |
| Nitrogen | ≤ 0.05% |
| Hydrogen | ≤ 0.015% |
| Other elements | ≤ 0.10% each |

Typical Applications
- Aerospace fasteners, springs, clips, retainers, and formed-wire components
- Medical device components and instruments where Ti-6Al-4V is specified
- High-performance industrial hardware requiring high strength and corrosion resistance
- Marine and chemical service components where higher alloy strength is beneficial
- Wire feedstock for additive manufacturing or joining when specified

Notes and Precautions
- Grade 5 has significantly higher strength than CP grades; confirm forming feasibility and required heat treatment route.
- For welding, use appropriate Ti-6Al-4V filler and strict inert gas shielding per your WPS to prevent contamination.
- Mechanical properties depend on diameter, condition, and heat treatment; specify tensile, elongation, and hardness targets when ordering.
