Titanium Fastener Materials & Grades Selection
Selecting the optimal titanium grade for industrial fastening components depends heavily on working temperatures, mechanical stress requirements, and environmental exposure. Almerca Titanium Industry Co., Ltd. supplies high-precision fasteners compliant with ASTM B348, ASTM F467/F468, DIN, ISO, and AMS standards.
| Titanium Grade | Material Characteristics | Typical Industrial Applications |
|---|---|---|
| Grade 2 Titanium | Commercially pure titanium with high ductility, excellent weldability, and superior resistance to chemical oxidation and seawater corrosion. | Desalination plants, marine equipment, chemical heat exchangers, offshore structures. |
| Grade 5 Titanium (Ti-6Al-4V) | Alpha-beta titanium alloy delivering outstanding tensile strength (tensile strength ≥ 895 MPa), low density, and high fatigue endurance. | Aerospace structural assemblies, racing vehicle chassis, engine components, turbine blades. |
| Grade 7 Titanium | CP titanium alloyed with 0.12%–0.25% Palladium, offering extreme resistance to reducing acids and localized crevice corrosion. | Flue gas desulfurization systems, pharmaceutical reactors, aggressive chemical processing. |
| Grade 23 Titanium (Ti-6Al-4V ELI) | Extra Low Interstitial variant of Grade 5, offering higher fracture toughness, damage tolerance, and biocompatibility. | Surgical implants, orthopedic devices, cryogenic pressure vessels, aerospace assemblies. |
Grade 5 (Ti-6Al-4V) High-Strength Titanium Fasteners
Grade 5 titanium fasteners (Ti-6Al-4V) represent over 70% of total commercial titanium fastener usage globally. Featuring an exceptional strength-to-weight ratio — nearly twice as strong as steel with only 57% of the weight — Grade 5 titanium bolts and screws eliminate weight constraints while preventing stress-corrosion cracking.
- Minimum Tensile Strength: 895 MPa (130 ksi)
- Yield Strength: 828 MPa (120 ksi)
- Operating Temperature Range: -250°C to +400°C
- Zero corrosion in salt spray and marine environments

Frequently Asked Questions (FAQ)
Q: What industries benefit most from using titanium fasteners?
A: Titanium fasteners are widely specified in aerospace engineering, offshore oil & gas platforms, marine vessel hardware, high-performance racing, medical implant devices, and chemical processing facilities where weight reduction and corrosion resistance are mandatory.
Q: What is the lead time for custom OEM titanium fastener production?
A: Standard stock items ship within 3–5 business days. Custom non-standard fasteners built from customer CAD drawings typically take 10 to 20 days depending on order quantity and special surface treatment requirements.
Q: Do you provide mill test certificates (MTC) with every order?
A: Yes. All shipments from Almerca Titanium Industry Co., Ltd. include official EN 10204 3.1 Material Test Certificates detailing chemical analysis, mechanical property test results, and batch traceability. Third-party testing by SGS or TÜV is also available upon request.
