Manufactured from vacuum-melted Grade 5 (Ti-6Al-4V) titanium bar stock using multi-axis CNC machining and high-speed cold-thread rolling. Designed to replace standard grade 8.8, 10.9, and 12.9 steel hardware with a 45% weight saving and lifetime immunity to harsh winter road deicing salts.
Automotive engineering hubs, specialized transport operators, and agricultural machinery retrofitters across the Gomel Region confront severe cyclic fatigue, sub-zero embrittlement, and aggressive salt corrosion. Here is the technical breakdown of how Grade 5 titanium alters structural longevity.
Standard grade 10.9 wheel bolts average a density of 7.85 g/cm³. Vunza Grade 5 titanium bolts register at 4.43 g/cm³—a direct 43.6% mass reduction at the wheel hub perimeter.
By reducing unsprung rotational mass, wheel hubs exhibit lowered polar moments of inertia, dampening high-frequency suspension oscillations and improving damper reaction time on uneven pavement across Gomel's regional road network.
Unlike workshops that simply lathe-turn threads, our Baoji facility implements cold thread rolling under high hydraulic pressure. This process reorients the material’s grain structure along continuous uninterrupted flow lines.
Cold rolling imparts compressive residual stresses at the thread roots, raising root fatigue life by over 350% compared to machine-cut bolts, preventing sudden fatigue cleavage under heavy lateral g-loads and cyclical braking shocks.
Winter temperatures in Gomel frequently drop below -20°C, causing conventional high-carbon alloy steels (such as 40Cr or 42CrMo) to enter ductile-to-brittle transition temperature (DBTT) zones, drastically increasing shear failure risks.
Ti6Al4V possesses a close-packed hexagonal (alpha) and body-centered cubic (beta) metallurgical phase that maintains outstanding Charpy V-notch impact toughness and elongation (≥ 10%) even down to cryogenic levels.
| Performance Parameter | Vunza Gr5 Titanium (Ti6Al4V) | High-Tensile Steel 10.9 | Grade 8.8 Structural Steel | Advantage for Gomel Fleets |
|---|---|---|---|---|
| Density (g/cm³) | 4.43 g/cm³ | 7.85 g/cm³ | 7.80 g/cm³ | 43.6% Weight Reduction |
| Tensile Strength Rm (MPa) | 950 – 1050 MPa | 1000 – 1040 MPa | 800 – 830 MPa | Equal to 10.9 Fasteners |
| Yield Strength Rp0.2 (MPa) | 880 – 920 MPa | 900 – 940 MPa | 640 – 660 MPa | High Elastic Clamping Range |
| Salt Spray Corrosion (ASTM B117) | > 2,500 Hours (Zero Rust) | 48–120 Hours (White/Red Rust) | 24–72 Hours (Rust Breakdown) | Immune to Calcium Chloride Road Salts |
| Thermal Expansion (10⁻⁶/K) | 8.6 (Matches Light Alloy Wheels) | 11.7 (Thermal Mismatch) | 12.0 (High Expansion Delta) | Eliminates Thermal Creep / Bolt Loosening |
Situated at a key commercial intersection of Belarus, Gomel boasts intensive mechanical production, agricultural tractor manufacturing, freight transit networks, and an active automotive racing subculture. Our specialized titanium fasteners are calibrated for these precise operating environments.
Gomel's enthusiast tuning workshops and regional rally sprint teams utilize our M12×1.25, M12×1.5, and M14×1.5 titanium wheel stud conversions and 12-point flange bolts. Replacing OEM lug bolts with titanium studs reduces unsprung hub weight on Audi, BMW, Porsche, and custom drift platforms. This sharpens steering turn-in response and eliminates stripped threads during fast pit-stop tire swaps in competitive racing events.
From November to April, municipal road authorities throughout Gomel and the southeastern Belarusian highway corridors (M8, M5, and M10 routes) heavily spread technical calcium chloride, magnesium chloride, and sodium chloride slurries. Standard zinc-plated and Dacromet-coated wheel bolts pit, seize, and fuse into alloy hubs. Titanium instantly generates a self-healing TiO₂ passivation film, making wheel bolt seizure physically impossible.
Gomel is a globally recognized manufacturing nucleus for combine harvesters, forestry machines, and heavy farm implements. In specialty guidance systems, high-speed rotary cutters, and seed distribution hubs, vibration-induced bolt fatigue is a major downtime catalyst. Our CNC-machined Grade 5 titanium flange bolts and studs provide sustained pre-load retention without shearing or vibrating loose under harsh mechanical shudder.
Located in Gaoya Village Industrial Zone, Baoji, Shaanxi—China’s world-renowned "Titanium Valley"—adjacent to the Baoti Group industrial base, Vunza Titanium Industry Co., Ltd. provides direct manufacturing capability with end-to-end traceability from raw titanium sponge to packaged fasteners.
Every production batch begins with certified vacuum arc remelted (VAR) titanium sponge. We supply full EN 10204 3.1 mill test certificates, spectral chemical analysis, and ultrasonic flaw detection reports with every export order to Belarus.
Our facility operates 34 sets of high-precision 3-axis, 4-axis, and simultaneous 5-axis CNC machining centers. We execute complex head contours, cross-drilled weight-reduction bores, and 12-point socket heads with repeatable precision down to 0.005 mm.
Whether you require DIN 74361 spherical collar wheel bolts for commercial hubs, 60° conical taper seats for aftermarket forged rims, or custom reverse-thread studs, our in-house engineering team provides DFM feedback and 3D modeling within 9 hours.
We manage streamlined logistics corridors connecting Xi'an/Baoji via China Railway Express (CR Express) directly to Belarusian freight customs depots, ensuring expedited bulk shipping, competitive DAP/DDP freight rates, and hassle-free customs clearance.
Detailed engineering answers covering metallurgical specifications, galling prevention, installation torques, logistics, and sample testing protocols for Belarusian procurement managers.
