Titanium Bolt Manufacturer & Supplier in China – Grade 5 Ti-6Al-4V Fasteners
Titanium bolts are widely used in aerospace, marine engineering, racing motorcycles, bicycles, chemical processing, medical devices, and high-performance industrial systems because they provide an exceptional combination of lightweight performance, high mechanical strength, and outstanding corrosion resistance. Compared with conventional stainless steel fasteners, titanium bolts can reduce component weight by nearly 45% while maintaining comparable or even superior strength levels. This unique balance makes titanium fasteners the preferred choice for engineers and OEM manufacturers seeking reliability in demanding environments.
At TSM Technology, we manufacture and supply a complete range of titanium bolts including DIN933 titanium hex bolts, DIN931 hex head bolts, DIN912 socket head cap screws, DIN7991 countersunk bolts, flange bolts, custom racing bolts, and aerospace titanium fasteners. Our titanium bolts are available in Grade 2, Grade 5 (Ti-6Al-4V), Grade 7, and Grade 23 titanium alloys according to ASTM B348, AMS 4928, DIN, ISO, and JIS standards.
What Are Titanium Bolts?
Titanium bolts are threaded fastening components manufactured from pure titanium or titanium alloy materials. Due to titanium's low density and excellent corrosion resistance, these bolts are extensively used in environments where traditional carbon steel and stainless steel fasteners fail because of rust, chloride corrosion, or excessive weight.
The most commonly used titanium bolt material is Grade 5 titanium alloy, also known as Ti-6Al-4V. This alloy contains aluminum and vanadium, giving it significantly higher tensile strength than commercially pure titanium while maintaining excellent fatigue resistance and corrosion performance. Grade 2 titanium bolts are also widely used in chemical processing and marine applications because of their superior corrosion resistance and weldability.
Unlike ordinary steel fasteners, titanium bolts form a stable oxide layer on the surface, which naturally protects the material from seawater corrosion, oxidizing acids, chloride ions, and industrial chemicals. This makes titanium fasteners ideal for offshore platforms, desalination systems, heat exchangers, and marine engineering projects.

| Aluminum (Al) | 5.5 – 6.75 |
| Vanadium (V) | 3.5 – 4.5 |
| Iron (Fe) | ≤ 0.40 |
| Oxygen (O) | ≤ 0.20 |
| Carbon (C) | ≤ 0.08 |
| Nitrogen (N) | ≤ 0.05 |
| Hydrogen (H) | ≤ 0.015 |
| Titanium (Ti) | Balance |
Grade 5 titanium alloy offers one of the best strength-to-weight ratios among engineering metals and is considered the industry standard for aerospace and high-performance fastening applications.
Mechanical Properties of Titanium Bolts
| Property | Grade 2 Titanium | Grade 5 Titanium |
|---|---|---|
| Tensile Strength | ≥ 345 MPa | ≥ 895 MPa |
| Yield Strength | ≥ 275 MPa | ≥ 828 MPa |
| Elongation | ≥ 20% | ≥ 10% |
| Density | 4.51 g/cm³ | 4.43 g/cm³ |
| Hardness | Moderate | High |
Compared with stainless steel bolts, Grade 5 titanium bolts provide excellent tensile strength while significantly reducing system weight. In racing and aerospace industries, this weight reduction improves acceleration, fuel efficiency, and mechanical response.
Titanium Bolt vs Stainless Steel Bolt
One of the most common questions from engineers and procurement specialists is whether titanium bolts are better than stainless steel bolts. The answer depends on the application environment.
| Comparison | Titanium Bolt | Stainless Steel Bolt |
|---|---|---|
| Weight | Very Lightweight | Heavy |
| Corrosion Resistance | Excellent in Seawater & Chlorides | Moderate |
| Strength-to-Weight Ratio | Excellent | Average |
| Magnetic Property | Non-Magnetic | Slightly Magnetic |
| High Temperature Resistance | Excellent | Moderate |
| Cost | Higher | Lower |
| Fatigue Resistance | Excellent | Moderate |
In marine and offshore environments, titanium bolts outperform stainless steel because titanium resists chloride-induced pitting corrosion. Stainless steel fasteners often fail in seawater systems due to crevice corrosion and rust formation, while titanium maintains long-term stability even under aggressive conditions.
Why Titanium Bolts Gall and How to Prevent It
Galling is a common engineering issue associated with titanium fasteners. Titanium has a strong tendency toward adhesive wear under friction, especially when titanium nuts and titanium bolts are tightened together without lubrication. During assembly, friction causes the metal surfaces to seize and damage the thread profile.
At TSM Technology, we recommend several methods to reduce galling risks:
- Use anti-seize lubricants during installation
- Reduce tightening speed
- Apply surface coatings such as PVD or anodizing
- Use rolled threads instead of cut threads
- Avoid excessive tightening torque
Rolled threads are especially important because cold-forming compresses the thread surface and improves fatigue resistance while reducing thread surface damage. Compared with machined threads, rolled threads can improve fatigue performance by approximately 30–40% in high-vibration applications.
