Titanium Ti-6Al-4V fastener grade 5

Description

1. Product Overview

Titanium Ti-6Al-4V Fastener (Grade 5) is a precision-engineered α+β titanium alloy fastener designed for critical structural joining where high strength-to-weight ratio, corrosion resistance, and fatigue performance are required. Primarily used in aerospace, defense, marine, and high-performance automotive assemblies, these fasteners enable weight reduction without compromising structural integrity. The key value proposition is delivering aerospace-grade mechanical properties (high tensile and yield strength, excellent fracture toughness) with predictable supply and batch traceability. Strategically, Ti‑6Al‑4V Grade 5 fasteners de-risk high-value projects by combining lifecycle cost savings from lighter structures and reduced maintenance with compliance to industry standards.

2. Key Specifications & Technical Characteristics

• Material: Titanium alloy Ti‑6Al‑4V (UNS R56400, Grade 5).

• Chemical composition (typical, wt%): Titanium bal.; Aluminum 5.5–6.75%; Vanadium 3.5–4.5%; Iron ≤0.3%; Oxygen ≤0.2%; Nitrogen ≤0.05%; Carbon ≤0.08%; Hydrogen ≤0.012%.

• Mechanical properties (typical heat-treated condition, note: supplied condition can be specified): Tensile strength 880–950 MPa; Yield strength 830–880 MPa; Elongation ≥10–15%; Hardness (HRC equivalent) dependent on finish.

• Density: ~4.43 g/cm³.

• Physical characteristics: Metallic silver-gray finish; available in standardized fastener forms (bolts, screws, studs, rivets, nuts) with precision threads to aerospace tolerances; surface finishes include natural passivated, passivated & oiled, or conversion-coated per customer spec.

• Corrosion resistance: Excellent in seawater, salt spray, and many industrial environments; non-magnetic.

• Tolerances: Manufactured to ASME/ISO metric and imperial fastener tolerances; custom tolerances available on request.

• Traceability & testing: Full batch traceability, mill certificates (EN 10204 3.1/3.2 available), mechanical test reports, chemical analysis, and non-destructive inspection reports (PT/UT/RT) as required.

• Surface treatments and coatings: Optional anodizing, electroless nickel, or MIL‑STD/AMS-approved coatings; passivation per AMS 2700 or equivalent.

• Packaging options: Bulk cartons, wooden crates, sealed kegs, or custom export pallets; inner anti-corrosion wrapping and desiccant; labeled with part number, lot, and certificate references.

• Shelf life: Indefinite under normal storage; recommended dry, temperature-controlled storage to preserve surface condition and coatings.

3. Core Industrial Applications

• Aerospace & Space: Structural airframe fastenings, landing gear subassemblies, engine mountings, and satellite structures. Chosen for high specific strength, fatigue resistance, and ability to meet stringent certification traceability.

• Defense & Military: Lightweight armored vehicle components, missile assemblies, and naval weapon systems where reliability under shock and cyclic load is essential.

• Marine & Offshore: Critical fastenings for subsea equipment, hull fittings, and corrosion-exposed assemblies that require long service life in saltwater environments.

• High-performance Automotive & Motorsport: Weight-sensitive chassis and suspension hardware delivering improved power-to-weight ratio and dynamic performance.

• Chemical & Process Industries: Fasteners for corrosion-prone environments and high-purity systems (e.g., heat exchangers, reactors) where contamination and corrosion resistance matter.
  Why it outperforms alternatives: Compared with stainless steels and high-strength steels, Ti‑6Al‑4V offers up to ~45–60% lower density with comparable strength, superior corrosion resistance, and better fatigue-to-weight performance. This translates to lower life-cycle costs through fuel savings (aerospace/automotive), reduced maintenance, and extended service intervals.

4. Competitive Advantages

• Quality consistency: Manufactured to certified aerospace/industrial standards with routine metallurgical inspection, mechanical testing, and statistical process controls.

• Supply reliability: Sourced from qualified mills with established production capacity, scalable batch runs, and safety-stock programs to support project timelines.

• Logistics capability: Export-ready packaging, consolidated LCL/FCL container shipping, expedited air freight options, and experienced customs documentation for global delivery.

• Price competitiveness: Volume-based pricing for bulk procurement and contract pricing models for multi-year programs; cost advantages realized through reduced life-cycle and maintenance expenses.

• Sustainability: Titanium’s long service life and recyclability reduce material replacement and waste; supply chain traceability supports ESG reporting.

• Technical support & documentation: Engineering support for fastener selection, torque/pretension guidance, compatibility assessments, CAD/technical drawings on request, and full compliance documentation (mill certs, test reports, inspection certificates).

5. Commercial & Supply Information

• Minimum order quantity (MOQ) BULK: 20 MT.

• Loading capacity (MT per container):

  • 20 ft container: up to ~20–22 MT (packaging dependent).

  • 40 ft container: up to ~24–26 MT (packaging dependent).

• Lead times: Standard production lead time varies with order size and finish specification; typical bulk lead 6–12 weeks from PO and technical sign-off. Expedited options available subject to surcharge.

• Incoterms, payment & logistics: Available under common Incoterms (FOB, CIF, EXW); payment terms and financing options negotiable for contracted volumes.

• Certifications available: Mill Test Reports (EN 10204 3.1/3.2), AS9100-aligned supply chain provenance, material certifications per AMS/ASTM specifications on request.
