Titanium axle nuts

Product Introduction 

Engineered from aerospace-grade Ti-6Al-4V (Grade 5 titanium), black titanium lug nuts deliver a tensile strength exceeding 950 MPa while weighing roughly 45% less than steel equivalents. This vacuum PVD black coating binds on a molecular level that is typical, producing a hardness of 2000-2500 Vickers for long-lasting scratch resistance. Titanium wheel nuts in both metric and imperial thread. We provide complete OEM/ODM support. Designed for performance, durability and accuracy. 

Technical Specifications

Product Application

Motorsport & Track Use: Reducing rotating mass directly affects lap times. Our black titanium wheel nuts are built for GT racing and time-attack environments where heat resistance at the hub is non-negotiable.

Luxury & Supercar Aftermarket: Porsche, Ferrari, McLaren, and BMW M-series builds benefit from the stealth black aesthetic and the elimination of galvanic corrosion between titanium nuts and forged aluminum wheels.

Coastal & Harsh Climate Fleets: In marine environments or regions with heavy road salting, titanium's passive oxide layer — reinforced by the PVD barrier — keeps black titanium lug nuts removable after years of exposure, avoiding costly torch-and-drill removal of seized steel hardware.

Why Choose Us / Manufacturing Capability

Steel lug nuts corrode, seize, and add unnecessary rotational mass. Our titanium lug nuts solve all three problems at once.

Grade 5 titanium (Ti-6Al-4V) offers a density of just 4.43 g/cm³ compared to steel's 7.85 g/cm³. That translates to roughly 2.5–3 lbs of saved rotational mass per vehicle — noticeably improving suspension response and handling precision.

The black PVD finish isn't paint. It's a vacuum-deposited ceramic-like layer (TiCN or TiAlN based) that won't chip, flake, or fade — even under impact wrench use or heavy braking heat exceeding 400°C.

Baoji Huacan operates from China's "Titanium Valley" in Baoji, Shaanxi — China's most concentrated titanium manufacturing hub.

Our facility includes 40+ CNC lathes, machining centers, and gantry systems with 10+ years of titanium machining experience. Annual production capacity exceeds 1,000 tons of finished titanium components, supporting 100+ international client collaborations across aerospace, automotive, and industrial sectors.

 

 

 

Manufacturing Process 

Each nut starts with verified Grade 5 titanium bar stock, inspected for chemical composition before machining begins.

CNC precision turning handles thread cutting, seat geometry, and outer profile with tight dimensional tolerances. Our 40+ CNC lathes and machining centers ensure consistent repeatability across both small batches and high-volume orders.

After machining, parts go through surface preparation and PVD coating in a vacuum chamber. This process molecularly bonds the black ceramic layer directly to the titanium substrate — no adhesives, no fillers.

FAQ

Q: How do titanium lug bolts compare to steel for everyday driving?

A: They provide identical clamping force with 45% less weight. You'll notice improved ride quality and easier wheel removal after years of service. The corrosion resistance eliminates rust-related maintenance issues common with steel fasteners.

Q: Will these bolts work with my vehicle's torque specifications?

A: Yes. Our Corrosion Resistant Titanium Lug Bolts accommodate standard automotive torque ranges from 80-140 Nm. The material properties support proper pre-load without thread deformation.

Q: Do I need special tools for installation?

A: Standard 17mm sockets work perfectly. Apply anti-seize compound sparingly to prevent galling. Torque to your vehicle manufacturer's specifications using a calibrated wrench.

Q: What makes Grade 5 titanium superior for this application?

A: The Ti-6Al-4V alloy balances strength, ductility, and corrosion resistance optimally. It maintains properties under thermal cycling while providing the lightest solution at required strength levels.

Q: How long do these bolts typically last?

A: With proper installation, expect 10+ years of service. The passive oxide layer regenerates continuously, maintaining corrosion protection indefinitely under normal conditions.

Q: Will the black finish chip with an impact wrench?

A：PVD coatings are molecularly bonded and won't flake. Using a soft-socket impact wrench is still recommended to preserve the surface long-term.

Q: Can titanium lug nuts seize to wheel studs?

A：Titanium can cold-weld under pressure. Always apply copper or nickel-based anti-seize to threads during installation — this fully eliminates the risk.

Q: Are factory torque specs compatible?

A：Yes. Grade 5 titanium is fully compatible with standard torque values (typically 85–110 ft/lbs). Titanium's elasticity actually helps maintain clamping force more consistently than steel.

Q: How do I clean the black finish?

A：pH-neutral soap and water is all you need. Avoid acidic wheel cleaners — they can degrade the PVD coating's hydrophobic properties over time.
