AMS 4928 Ti6Al4V Rod – Aerospace-Grade Titanium Alloy Bar
In accordance with aerospace-grade requirements, LINHUI TITANIUM provides quality AMS 4928 Ti6Al4V Rod. It offers Ti6Al4V (Grade 5) titanium alloy bar and wire in diameters ranging from 1 mm to 152.4 mm. With a minimum tensile strength of 130 ksi (896 MPa) and a yield strength of 120 ksi (827 MPa), our Rod satisfies strict fracture toughness criteria.
Every rod is subjected to microstructure verification to rule out alpha case and 100% ultrasonic testing in accordance with AMS 2631. Our materials guarantee high fatigue resistance for flight-critical components with a regulated interstitial content (hydrogen <0.0125%). With comprehensive EN 10204 3.1 traceability certificates, factory-direct supply allows stock orders to be delivered in 3–7 days.
Key Features & Benefits
Superior Strength-to-Weight Ratio
AMS 4928 Ti6Al4V Rod delivers exceptional mechanical performance at just 4.43 g/cm³ density. You gain 30% weight savings over steel while maintaining structural integrity in dynamic loading conditions.
Enhanced Fatigue Resistance
Our strictly controlled alpha-beta microstructure prevents continuous grain boundary networks. This eliminates premature crack initiation in cyclic stress environments like turbine engines and rotating assemblies.
Thermal Stability
Maintains mechanical properties up to 400°C (750°F). You can rely on dimensional stability and strength retention in elevated-temperature applications without material degradation.

Manufacturing Process
Vacuum Arc Remelting (VAR)
We employ triple-melt VAR processing to eliminate high-density inclusions. This creates a homogeneous microstructure free from segregation defects.
Hot Forging & Rolling
Billets undergo controlled hot working at precise temperatures. This refines grain size and optimizes the alpha-beta phase distribution for balanced strength and ductility.
Centerless Grinding
Final diameter control achieves h8/h9 tolerances (±0.002 inches). Surface grinding removes forging skin and alpha case, delivering ready-to-machine rods with consistent dimensions.
Quality Inspection
100% Ultrasonic Testing (UT)
Per AMS 2631 Class A standards, every rod receives longitudinal ultrasonic inspection. This detects internal voids, HDI, or discontinuities before shipment.
Microstructure Verification
Metallographic examination confirms the absence of alpha case and continuous grain boundary networks. You receive material with predictable fatigue life and machinability.
Chemical Analysis
Inert Gas Fusion (IGF) validates hydrogen content below critical thresholds. Each heat undergoes spectroscopy to verify compliance with AMS 4928 chemistry limits.
Applications
Aerospace Turbine Engines
Your compressor blades and disks benefit from exceptional creep resistance and vibration damping. AMS 4928 Ti6Al4V Rod withstands high rotational forces while enabling precision aerodynamic profiles.
Airframe Structural Fasteners
High shear strength prevents joint failure in composite-metal assemblies. The material resists stress corrosion cracking in marine and atmospheric exposure conditions.
High-Performance Automotive
Formula 1 teams machine connecting rods and valve components from our rods. Reduced reciprocating mass allows higher RPMs while surviving extreme thermal cycling and mechanical shock.
Export Markets
More than 60 countries have received hundreds of thousands of tons of LINHUI Titanium. Our is used by precision machining facilities and aerospace manufacturers in North America, Europe, and the Middle East.
The United States, Germany, France, Canada, Japan, and the United Arab Emirates are important markets. We continue to collaborate with international aircraft OEMs and EPC contractors who need materials that are FDA, PED, and NORSOK compliant.

FAQ
Q: What differentiates AMS 4928 Ti6Al4V Rod from ASTM B348 Grade 5?
A: AMS 4928 requires stricter microstructure controls, higher ultrasonic inspection frequencies, and tighter mechanical testing intervals than general industrial ASTM B348 standards.
Q: Can the strength of the rod material be improved through heat treatment?
A: Yes. While supplied annealed, the alloy accepts solution treatment and aging (STA) to increase strength. However, AMS 4928 specifically certifies the annealed condition.
Q: How do you prevent alpha case formation?
A: We remove alpha case via centerless grinding and acid pickling before shipment. Transverse microstructure tests confirm complete removal.
Q: What diameter tolerances do you achieve?
A: Precision ground rods hold h8 or h9 tolerances (±0.002 inches), compatible with Swiss-style CNC lathes for high-volume fastener production.
Q: What is your typical lead time?
A: Stock orders ship within 3–7 days. Standard production requires 15–25 days, while custom fabrications take 25–40 days. Rush orders accommodate urgent project schedules.
