AMS 4911 Ti6Al4V Titanium Alloy Rod
Aerospace-grade AMS 4911 Ti6Al4V titanium alloy rod that has been confirmed to satisfy AMS 4911 requirements is offered by LINHUI Titanium. Our Ti-6Al-4V (Grade 5) rods have an exceptional strength-to-weight ratio and corrosion resistance, and they can tolerate temperatures as high as 750°F (400°C). These rods offer outstanding fatigue resistance for flight-critical applications, with minimum tensile strengths of 130 ksi (896 MPa) and yield strengths of 120 ksi (827 MPa). Hydrogen embrittlement is prevented by strict chemical composition control, which includes oxygen ≤0.20% and hydrogen ≤0.015%. Our annealed rods are perfect for precise machining and superplastic shape because to their homogeneous microstructure.--- Principal Attributes & Advantages.

Manufacturing Process
Vacuum Arc Remelting (VAR)
Triple-melt process eliminates inclusions and ensures chemical homogeneity throughout the billet.
Precision Hot Rolling
Controlled rolling parameters maintain uniform grain structure. Temperature monitoring prevents alpha-case formation.
Stress-Relief Annealing
Heat treatment at controlled atmosphere furnaces delivers consistent mechanical properties. Cooling rates are optimized for alpha-beta phase balance.
Alpha-Case Removal
Chemical milling removes brittle oxygen-enriched surface layers, ensuring crack-free performance under cyclic loading.
Quality Inspection
Complete Ultrasonic Examination (AMS 2631)
Internal discontinuities as small as 0.8 mm in diameter can be found using volumetric scanning.
Tensile Examination (ASTM E8)
Every production lot's mechanical property compliance is confirmed by longitudinal and transverse specimens.
Analysis of Hydrogen Content
To avoid embrittlement, vacuum hot extraction verifies that the H content is less than 0.015%.
Metallographic Analysis
Alpha-beta phase distribution and zero alpha-case presence are confirmed by microstructure investigation.
Applications
Structural Elements of Aerospace
Wing brackets, fuselage ribs, and airframe stringers all have great fatigue resistance and reduce weight.
Superior Automotive Performance
Corrosion resistance under high vibration is used in Formula 1 suspension push-rods and chassis brackets.
Equipment for Industrial Manufacturing
Sonotrodes for ultrasonic welding use acoustic transmission characteristics to operate at high frequencies for extended periods of time.
Hardware for the Military
Export Markets
Asia-Pacific (Japan, South Korea, Singapore), the Middle East (UAE, Saudi Arabia), the European Union (Germany, France, UK), North America (USA, Canada), and South America (Brazil).---

FAQ
Q: What distinguishes ASTM B348 Grade 5 from AMS 4911?
A: Stricter interstitial element restrictions and required lot testing are enforced by AMS 4911, guaranteeing aerospace-grade reliability above and beyond commercial norms.
Q: Is it possible for you to offer specially cut lengths?
A: Yes. We provide waterjet or sawing precision cutting to your desired dimensions with a tolerance of ±0.5mm.
Q: Are you in favor of third-party inspection?
A: Definitely. You can request SGS, BV, TÜV, DNV, and ABS examinations prior to shipment.
Q: How long does it usually take you?
A: Stock products take three to seven days to ship. 15 to 25 days are needed for custom orders. On request, rush manufacture is available.
Q: Is heat treatment required after welding?
A: Stress-relief annealing at 1000–1100°F is advised for important aircraft assemblies in order to eliminate residual stress and recover ductility.---
