Electro-Thermal Vacuum Micro-Oxidation
Manufactured from Baoji-certified Grade 5 titanium bars. Fully threaded, cold-forged and precision-machined to resist extreme road shear stress and tropical oxidation across the Red River Delta corridor.
Hanoi’s unique climate blends extreme relative humidity (frequently exceeding 85%), seasonal monsoons, road inundation, and dense stop-and-go urban traffic. Standard zinc-plated or mild stainless steel bolts succumb quickly to galvanic pitting and chloride oxidation.
In motorcycle hubs like Cau Giay, Dong Da, and Hai Ba Trung, high-displacement underbones (Yamaha Exciter 155, Honda Winner X) and premium maxi-scooters (SH150i) undergo extensive customization. Our burnt blue Gr5 bolts deliver vital unsprung weight reduction on front fork triple clamps, brake rotor carriers, and master cylinders while delivering an unmistakable iridescent motorsport aesthetic.
During the northern rainy season, Hanoi's ring roads and low-lying avenues face sudden flood surges laden with urban run-off and road contaminants. Ordinary A2/A4 stainless fasteners undergo severe crevice corrosion inside aluminum engine casings. Titanium forms an instantaneous, regenerative TiO2 passivation film that remains completely impervious to wet galvanic decay.
Navigating Hanoi's rush-hour traffic along the Ring Road 3 overpass induces severe thermal build-up inside air-cooled and liquid-cooled engine blocks. Our burnt blue M8 exhaust manifold studs withstand cyclical thermal spikes up to 600°C without galling, embrittlement, or surface degradation, maintaining nominal clamping force indefinitely.
True technical value lies in structural yield, weight savings, and lifecycle fatigue resistance. See why professional race teams and discerning tuning shops across Northern Vietnam transition to cold-forged Gr5 titanium.

*Mechanical tests conducted in accordance with ASTM B348, ASTM F136, and ISO 898-1 standard practices. Every batch dispatched to Vietnam includes full mill test certification (MTR) with verified optical emission spectrometry chemical breakdowns.
Vietnam is one of the world's fastest-growing motorcycle markets per capita. The aftermarket procurement pattern in Hanoi is experiencing critical shifts toward engineering integrity and high-aesthetic titanium upgrades.
The swift adoption of premium electric scooters (such as VinFast Theon, Feliz S, and custom builds) has created severe demand for lighter structural hardware to offset heavy lithium battery packs without compromising chassis rigidity.
Vietnamese builders increasingly reject low-tier immersion-anodized screws that discolor under intense UV exposure and road grime, favoring vacuum-deposited PVD burnt blue finishes with surface hardness above 2200 Vickers.
Wholesale distribution hubs along Pho Hue and Cho Troi are replacing domestic middleman supply chains with direct container and consolidated LCL air-cargo shipments straight from Baoji manufacturing centers to Haiphong / Noi Bai.
High-end workshops are mandating complex head geometry—such as drilled safety wire flanges, flower/umbrella heads, and internal Torx recesses—that cannot be produced via conventional cold forging alone.
Located on Yucai Road in the High-tech Development Zone of Baoji—China’s internationally renowned Titanium Valley—Navzo Precision Titanium combines short raw material supply chains with multi-axis CNC machining centers.
We source prime virgin sponge titanium transformed into Ti-6Al-4V bar stock under strict aerospace standards. Mill test reports (EN 10204 3.1) are standard with every production batch to verify chemical purity and tensile yield.
Our workshop integrates high-speed multi-station cold heading machines, thread-rolling dies, and CNC Swiss lathes capable of achieving thread tolerance Grade 6g and concentricity within ±0.01mm.
Our signature burnt blue coloration is achieved through calibrated thermal diffusion oxidation combined with physical vapor deposition (PVD). The resulting layer will not peel, flake, or degrade under direct contact with DOT4 brake fluids.
Every single lot undergoes optical projector dimension checking, Go/No-Go thread pitch gauge verification, torque destructive analysis, and salt spray fog resistance testing prior to vacuum packaging.
Strategically linked to primary freight transit networks. We facilitate rapid door-to-door express couriers (DHL/FedEx, 3-4 days to Hanoi) or cost-effective land/sea multimodal consolidation through Pingxiang / Lang Son border checkpoints.
Time zones align directly with Vietnam (UTC+7). Our export engineering department operates in real-time, providing immediate 2D/3D technical feasibility reviews and competitive tiered wholesale quotations.

Counterfeit parts are rampant in low-cost open retail markets. Verification is simple through three empirical methods: (1) Density check: Titanium has a density of ~4.43 g/cm³, nearly half that of stainless steel (7.9 g/cm³); (2) Spark testing: When touched lightly to an abrasive grinding disc, Gr5 titanium generates brilliant, intense white sparks, whereas steel emits orange/yellow sparks; (3) Magnetic test: Titanium is completely non-magnetic.
No. Our burnt blue finish is not a painted enamel, powder coating, or organic dye. It is created through controlled electro-chemical oxidation or vacuum physical vapor deposition (PVD), forming an atomic-level oxide ceramic barrier (TiO2). It is chemically stable and completely unaffected by concentrated alkaline snow-foam soaps, gasoline splashes, or brake dust solvents.
Because titanium has a low modulus of elasticity (~114 GPa) and can undergo cold galling against aluminum under heavy dry torque, always apply a thin layer of nickel-based or copper-based anti-seize paste to threads. When torquing Gr5 fasteners, reduce the dry OEM factory torque specification by approximately 10% to 15% to compensate for reduced thread friction.
We routinely export to Vietnam. For sample batches and urgent express orders, we ship via DHL/FedEx with an average transit time of 3 to 5 business days to your door in Hanoi. For wholesale distributor cargo, shipments can be routed overland via the Guangxi–Lang Son border gate or via sea freight to Haiphong Port. Under the ACFTA (Form E), titanium fasteners benefit from preferential import duty tariffs.
Yes. Send us your CAD drawings (PDF, DWG, STEP) or physical sample bolts. Our facility features custom tool-grinding and 5-axis CNC capability to produce custom hollowed heads, umbrella caps, slotted flanges, reverse threads, or ultra-fine pitches (e.g., M10x1.0, M12x1.25) with minimum order quantities as low as 100-200 pieces per size.
Torx drives (such as our T30 bolts) distribute rotational torque across six broad lobes rather than sharp 60° corners. In high-torque applications like brake disc rotors, Torx profiles virtually eliminate tool cam-out and stripped bolt heads during high-speed pneumatic assembly, making them the preferred choice for performance garages.
