🛠 Material Excellence – Ti-6Al-4V (Grade 5 Titanium)
Chemical Composition
| Element | Content (wt%) | Purpose |
|---|---|---|
| Titanium (Ti) | Balance | Base metal, corrosion resistance |
| Aluminum (Al) | ~6.0 | Strength enhancement, α-phase stabilizer |
| Vanadium (V) | ~4.0 | Toughness and ductility, β-phase stabilizer |
Key Mechanical Properties
| Property | Typical Value |
|---|---|
| Density | 4.43 g/cm³ |
| Tensile Strength | ≥ 895 MPa |
| Yield Strength | ≥ 828 MPa |
| Elongation | 10–14% |
| Hardness | 36–38 HRC |
| Melting Point | 1660°C |
These properties make the Ti-6Al-4V screw an optimal choice for high-performance fastening solutions where both strength and corrosion resistance are essential.
🚀 Core Advantages
🔹 1. Unmatched Corrosion Resistance
The naturally forming TiO₂ oxide layer protects the GR5 Titanium Screw from seawater, chlorides, and a wide range of chemicals, making it far superior to stainless steel in harsh conditions.
🔹 2. Superior Strength-to-Weight Ratio
A titanium alloy screw weighs about 45% less than an equivalent stainless steel fastener, helping engineers reduce overall system mass without compromising strength.
🔹 3. High Temperature Stability
The GR5 titanium fastener retains mechanical integrity at temperatures exceeding 350°C, outperforming aluminum and many other metal fasteners in elevated-temperature applications.
🔹 4. Fully Customizable
Our customized titanium screw options include thread form, head type, surface finish, and specialized coatings for unique environments.

🧩 Engineering Guidelines
Clamp Load & Torque
The preload of a Ti-6Al-4V screw depends on surface finish, lubrication, and thread pitch. We recommend moly-based lubricants for torque stability.
Fatigue Life Optimization
Generous fillets, under-head radii, and shot peening can significantly extend the service life of each titanium alloy screw in cyclic loading applications.
Galvanic Corrosion Control
When pairing with carbon fiber or dissimilar metals, use isolation washers to prevent galvanic coupling.
