Manufactured by Jiaxing Wexra Titanium Products Co., Ltd. for extreme mechanical reliability, bio-inert stability, and low-mass requirements. Below are 8 flagship precision assemblies currently exported to European distribution partners.
Self-locking flanged lock nuts engineered in Ti-6Al-4V Grade 5 for dynamic vibration dampening. Provides superior clamp-load retention across heavy cyclic fatigue environments.
Multi-gauge high-tensile flanged bolts featuring zero-build electrolytic oxide layers. Resists harsh atmospheric chemical corrosion and galvanic degradation in complex assemblies.
Mirror-polished 12-point precision bolts with rolled threads for enhanced shear resilience. Ideal for structural brackets, calipers, and precision kinematic linkages.
Low-profile disc head configuration offering expansive surface contact area. Distributes axial clamping force evenly over fragile composite or metallic substrates.
Precision internal hex (Allen) oval head fastener. Designed for flush mechanical fitment where clearance is restricted and minimal aerodynamic drag or tissue irritation is needed.
Engineered to DIN standards in Grade 9 and Grade 5 titanium, balancing ductile compliance with massive yield strength for critical structural load-bearing components.
Ultra-sharp flute geometry with micro-pitch lead threads. Ideal for automated self-tapping into pre-drilled porous media, synthetics, and cortical bone mimics without stripping.
Multi-flute Torx socket geometry engineered for extreme drive-torque transmission. Eliminates cam-out risks during critical orthopedic and automated robotic fastening runs.
Espoo stands as Finland’s undisputed beacon of high-technology research, home to Otaniemi’s deep-tech clusters, VTT Technical Research Centre of Finland, and pioneering medical hardware incubators. As the medical and bio-engineering landscape shifts toward minimally invasive surgical techniques, bio-inert osteosynthesis, and customized patient-specific fixations, the demand for precision-machined titanium hardware has escalated dramatically.
Jiaxing Wexra Titanium Products Co., Ltd. serves purchasing heads, precision device manufacturers, and medical research developers throughout Espoo and the greater Uusimaa region. Leveraging an ISO 9001:2015-certified manufacturing plant with tight multi-axis CNC swiss-machining centers, our facility delivers titanium bone screws, locking plates, cannulated fixations, and custom micro-machined titanium components that satisfy rigorous biological and mechanical specifications.
| Material Grade | Yield Strength (Rp0.2) | Tensile Strength (Rm) | Elongation (%) | Modulus of Elasticity | Biocompatibility & Corrosion Profile |
|---|---|---|---|---|---|
| Ti-6Al-4V Grade 5 (ELI - ASTM F136) | ≥ 795 MPa | ≥ 860 MPa | ≥ 10% | ~ 110 - 114 GPa | Zero cytotoxicity; thick spontaneous TiO2 passivation; optimal for load-bearing cortical screws. |
| CP Titanium Grade 2 (ASTM F67) | ≥ 275 MPa | ≥ 345 MPa | ≥ 20% | ~ 105 GPa | Maximum ductile deformability; ideal for low-stress cranial, maxillofacial, and dental anchor pins. |
| CP Titanium Grade 4 | ≥ 480 MPa | ≥ 550 MPa | ≥ 15% | ~ 105 GPa | High strength unalloyed titanium; free from vanadium and aluminum traces for pure metallic integration. |
| AISI 316L Stainless Steel (Reference) | ~ 290 MPa | ~ 620 MPa | ≥ 35% | ~ 193 GPa | High density (7.9 g/cm³); susceptibility to fretting corrosion in saline bio-fluids; higher modulus mismatch. |
A primary failure mode in bone-anchored fixations stems from the "stress shielding" effect caused by elastic modulus mismatch. High-strength steel hardware possesses a Young's modulus nearly double that of titanium alloys (~193 GPa versus ~110 GPa). When implanted, steel carries disproportionate axial stress, which shields the surrounding bone from the mechanical loading necessary to trigger Wolff's Law of bone remodeling. Our Ti-6Al-4V Grade 5 and ELI titanium screw solutions significantly mitigate this stiffness gradient, encouraging superior osseointegration, rapid callus formation, and structural stabilization.
Our raw material bars originate strictly from vacuum arc remelted (VAR) titanium billets accompanied by 3.1 Mill Test Certificates. Trace interstitial elements such as iron, oxygen, and carbon are kept below clinical ELI (Extra Low Interstitial) thresholds to ensure fracture toughness under torsional loads.
Rather than cut threads that sever metallic grains, our high-precision thread rolling procedures compress and reorient the titanium microstructure along thread flanks. This cold-forming process elevates surface hardness, mitigates micro-fissuring, and enhances fatigue endurance by up to 35%.
Our finished components undergo automated ultrasonic degreasing, clean-room acid pickling, and controlled Type II electrolytic anodizing. This eliminates free iron contaminants and establishes a chemically stable, non-shedding titanium oxide barrier.
Espoo's intersection of health technology, university-backed robotics, and Nordic marine engineering creates specialized, high-reliability deployment environments for our titanium products:
Procurement strategies in the Finnish and Scandinavian high-tech sectors are being reshaped by strict supply chain visibility, regulatory transparency, and environmental impact assessments.
With the full implementation of EU MDR 2017/745, Espoo-based medical engineering buyers require complete lot traceability from raw melt to final dispatch. Wexra maintains rigid documentation, supplying complete chemical assay breakdowns, ultrasonic inspection certificates, and batch control records with every delivery.
While 3D printed porous titanium cages and osteoconductive lattices flourish in Espoo's laboratories, additive manufacturing cannot replicate the ultra-sharp thread crests and fatigue resilience of rolled screw threads. The market is shifting to hybrid protocols: 3D-printed scaffolds anchored by ultra-precise CNC rolled-thread titanium screws.
European distributors are actively diversifying beyond vulnerable raw material monopolies. By collaborating directly with our specialized Jiaxing production hubs, Finnish buyers obtain direct factory-floor pricing, guaranteed delivery timetables, and custom OEM packaging adapted to European EPR regulations.
Founded in 2018 in Jiaxing, Zhejiang, Jiaxing Wexra Titanium Products Co., Ltd. has developed into a dedicated manufacturer and exporter of precision Grade 2 and Grade 5 (Ti-6Al-4V) components. Our company profile, testing facilities, and export record directly address the critical quality thresholds demanded by top-tier European buyers:
