Selecting the correct titanium grade ensures mechanical reliability and corrosion resistance tailored to your operating environment.
Grade 5 Titanium (Ti-6Al-4V)
The primary choice for high-strength applications. It offers a tensile strength of approximately 895 MPa and a density of 4.43 g/cm³, delivering an optimal strength-to-weight ratio for aerospace and precision machinery.
Grade 2 Titanium (Commercially Pure)
Selected for applications demanding maximum chemical and seawater resistance. It provides excellent ductility and stable performance in chloride-rich environments.
Grade 7 & Grade 9
Grade 7 incorporates palladium for enhanced crevice corrosion resistance in aggressive chemical processing, while Grade 3Al-2.5V (Grade 9) provides higher strength-forging capabilities for specialized industrial tubing and structures.
Corrosion Resistance Without Surface Coatings
Unlike carbon steel fasteners that rely on electroplated or painted coatings to prevent oxidation, titanium naturally forms a dense, self-healing titanium dioxide (TiO₂) passive film instantly upon exposure to oxygen.
Operational Benefit: Eliminates rust-related joint failure in marine atmospheres, acidic/alkaline process streams, and high-humidity washdown areas, significantly lowering long-term maintenance frequency.
Weight Reduction & High Strength-to-Weight Ratio
Titanium delivers structural strength comparable to alloy steels at nearly 60% of the weight (approx. 40% lighter).
Operational Benefit: Reduces dynamic loads on moving parts, improves energy efficiency in high-speed reciprocating machinery, and simplifies manual handling during large-scale assembly.
Plastic Mold Reliability & Maintenance Reduction
In injection molding and precision tooling, fasteners face thermal cycling, cooling water exposure, residual moisture, and aggressive mold-release agents.
Operational Benefit: Titanium socket head cap screws and mold base fasteners prevent rust-seizing and coolant-induced thread degradation, directly reducing downtime during mold servicing and part changes.
We machine fasteners from bar stock and forged blanks to international standards or customized customer blueprints.
Titanium Screws
Socket head cap, button head, flat countersunk, machine, and self-tapping configurations for precision equipment and mold inserts.
Titanium Bolts
Hex head, heavy hex, flange bolts, and shoulder bolts engineered for high load-bearing structural joints.
Titanium Nuts & Studs
Standard hex nuts, nylon insert lock nuts, flange nuts, and fully threaded studs/rods built for stable, repeated assembly cycles.
Thread Standards
Metric series (M), Unified National Coarse/Fine (UNC/UNF), and custom thread pitches.
To optimize friction coefficients and assembly performance, we offer specialized post-machining treatments:
Polished Finish
Removes machining burrs and surface contaminants for cleanroom compatibility and visual inspection.
Anodizing (Type II)
Provides light surface passivation and color-coding identification for assembly tracking.
Thread Lubrication / Anti-Galling Treatment
Crucial for titanium assemblies. Because titanium has a high coefficient of friction under sliding contact, specialized coatings or thread lubricants prevent thread galling (cold welding) during high-torque installation.
Quality Inspection Protocols
Given the strict mechanical demands of titanium components, our internal quality control system tracks every production batch through four sequential checkpoints:
Material Verification: Positive Material Identification (PMI) and chemical composition analysis to confirm raw stock grade compliance (supported by internal laboratory spectrometry and certified testing).
Dimensional Control: Optical comparators and thread plug/ring gauges to verify pitch diameter, major/minor diameters, and length tolerances (verified via high-precision CMM inspection).
Mechanical Testing: Tensile, hardness, and proof-load testing performed per project requirements.
Documentation: Mill Test Certificates (MTC) and dimensional inspection reports supplied upon request.
Supply Chain Flexibility (MOQ & Lead Time)
Standard Stock Items: Low Minimum Order Quantities (MOQ) with fast dispatch options for standard metric and UNC/UNF sizes.
Custom Production: Flexible production scaling for OEM projects, with typical manufacturing lead times provided upfront upon engineering drawing review.
