what is TI6AL4V titanium lug bolts?
TI6AL4V titanium lug bolts are high-performance fasteners made of titanium alloy (typically Ti-6Al-4V). Compared to traditional steel bolts, they offer significant advantages such as lightweight, high strength, and corrosion resistance, and are widely used in racing, supercar modification, and high-end motorcycles.
TI6AL4V titanium lug bolts are the ultimate choice for high-performance modifications, offering irreplaceable advantages in lightweight design, corrosion resistance, and temperature adaptability. However, their high price and stringent installation requirements make them more suitable for track enthusiasts and those seeking the ultimate modification experience. For ordinary users, choosing high-quality steel bolts and proper installation can also ensure safety and reliability.
Main materials
Ti-6Al-4V, GR5: The most commonly used, with a tensile strength ≥895–1100 MPa and a density of 4.51 g/cm³ (approximately 60% of steel), balancing strength, toughness, and machinability.
TA6V (Ti-6Al-2Sn-4Zr-2Mo): Higher temperature and fatigue resistance, used in racing tracks/extreme conditions.
Ti-3Al-2.5V: Focuses on fatigue resistance and corrosion resistance, suitable for long-term vibration environments.
Key performance parameters (taking M12×1.5 as an example)
- Lightweight: Each piece weighs approximately 28g (compared to approximately 48g of steel of the same specification), resulting in a weight reduction of 40%–50%; the total unsprung mass of 20 pieces in the vehicle is approximately 400g, leading to a weight reduction of approximately 4kg for the vehicle's handling.
- Strength: Tensile strength ≥900MPa, yield strength ≥830MPa, reaching the level of 10.9–12.9 grade steel bolts.
- Fatigue: 10⁷ cycle fatigue limit ≥450MPa, approximately twice that of 45 steel.
- Corrosion Resistance: Salt spray test **≥1000–5000h** with no rust, far exceeding 316L stainless steel.
- Temperature: Long-term resistance **-50℃~300℃, short-term resistance to 580℃+** (high temperature braking).
- Non-magnetic: Does not interfere with electronic systems, suitable for electric vehicles/new energy vehicles.
7. Production process: Titanium alloy bar → Hot forging/cold heading → CNC machining → Thread rolling
→ Heat treatment (solution treatment ) → Surface treatment → Quality inspection

performance advantages
1. Extremely Lightweight Performance
Single Bolt Weight: M14 titanium alloy bolt approximately 35-45g, compared to approximately 65-80g for steel bolts of the same specification.
Overall Vehicle Weight Reduction: A set of 20 pcs bolts can reduce weight by 400-600g.
Unsprung Mass: Reduces rotational mass, improving acceleration/deceleration response.
2. Excellent Corrosion Resistance
A dense TiO₂ oxide film forms on the titanium surface, offering far superior salt spray corrosion resistance compared to galvanized steel.
Suitable for coastal areas and roads exposed to salt in winter.
No risk of electrochemical corrosion (good compatibility with aluminum wheels).
3. Temperature Adaptability
Good strength retention at high temperatures, suitable for high-performance braking systems.
No embrittlement at low temperatures, reliable in extreme environments.
