Chemical Composition of Ti-6AL-4V
When we evaluate the performance of Ti-6AL-4V alloy, it all comes down to its precise chemical makeup. Widely recognized as Grade 5 Titanium or the Ti64 material, this alloy blends titanium with specific amounts of aluminum and vanadium to drastically improve its physical characteristics compared to commercially pure grades.
Here is the standard chemical composition breakdown that makes this material an industry workhorse:
- Aluminum (Al): 5.50% – 6.75% (Stabilizes the alpha phase, increasing overall strength)
- Vanadium (V): 3.50% – 4.50% (Stabilizes the beta phase, enhancing formability and heat treatability)
- Iron (Fe): 0.40% max
- Oxygen (O): 0.20% max
- Carbon (C): 0.08% max
- Nitrogen (N): 0.05% max
- Hydrogen (H): 0.015% max
- Titanium (Ti): Balance
Keeping trace elements like oxygen, carbon, and iron strictly controlled ensures our Titanium 6AL-4V maintains its high strength-to-weight ratio without compromising ductility. This tightly regulated elemental balance is exactly what guarantees reliable, repeatable performance across high-stress manufacturing environments.
Mechanical & Physical Properties of Ti-6AL-4V Alloy
When we evaluate Ti6Al4V mechanical properties, it is easy to see why this is the premier high strength-to-weight ratio metal for demanding American industries. It consistently delivers steel-like strength at nearly half the weight, making it highly efficient for structural applications.
Tensile Strength, Yield Strength, and Elongation
This Ti64 material is engineered to handle extreme stress and heavy loads without failing.
- Ultimate Tensile Strength: ~130,000 psi (896 MPa)
- Yield Strength: ~120,000 psi (827 MPa)

Hardness Specifications
Titanium 6AL-4V is incredibly tough, offering excellent wear resistance right out of the mill.
- Rockwell Hardness: ~36 HRC
- Brinell Hardness: ~334 HB
Because of this inherent toughness and high hardness rating, utilizing rigid setups and proper tooling during CNC machining is critical to maintain tight tolerances and prevent rapid tool wear.
Density, Melting Point, and Thermal Conductivity
The physical characteristics of the Ti-6AL-4V alloy dictate how it performs under extreme heat and environmental pressure.

The versatility of Ti-6AL-4V alloy makes it the most widely used titanium grade across global industries. Because this Ti64 material offers an exceptional strength-to-weight ratio and outstanding corrosion resistance, we regularly supply it for some of the most demanding applications in the world.
- Aerospace & Defense: As a premier aerospace titanium alloy, it is critical for manufacturing turbine blades, robust airframe components, and high-performance engine parts. Engineers frequently rely on it when navigating the strict properties of heat-resistant metals required for modern flight and defense systems.
- Medical & Dental: Recognized as a top-tier medical grade titanium, this alloy is perfectly suited for life-saving orthopedic implants, precision surgical instruments, and durable dental prosthetics due to its exceptional biocompatibility and strength.
- Automotive & Motorsports: In high-speed racing and premium automotive manufacturing, Grade 5 Titanium significantly reduces vehicle weight without sacrificing structural integrity. It is commonly machined into connecting rods, engine valves, and advanced suspension components.
- Marine & Offshore: Saltwater environments quickly degrade standard metals, but Titanium 6AL-4V thrives in these conditions. It is widely specified for deep-water subsea equipment and heavy-duty propeller shafts. When evaluating materials for harsh saltwater exposure, understanding their practical applications and magnetic properties is essential for ensuring long-term offshore project success.
Titanium Machining Guidelines & Fabrication
Working with Ti-6AL-4V alloy requires specific techniques because of its high strength and low thermal conductivity. We rely on proven fabrication methods to get the most out of this versatile material without rapidly burning through tooling.
CNC Machining Best Practices
Because Ti64 material tends to gall and generate intense heat right at the cutting edge, much like other top heat-resistant metals for extreme temperature use, proper CNC setup is mandatory.
- Tooling: Stick to premium carbide tools with sharp, positive cutting edges. Replace tools at the first sign of wear.
- Speeds & Feeds: Run low cutting speeds combined with heavy, continuous feed rates. This prevents the material from work-hardening and keeps the tool moving through the metal.
- Coolant: Flood the cutting zone. High-volume, high-pressure water-soluble cutting fluids are absolutely essential to flush away chips and pull heat out of the tool.
Welding Grade 5 Titanium
This titanium alloy is highly weldable, but it demands strict environmental control. Gas Tungsten Arc Welding (GTAW/TIG) is our standard approach.
- Filler Metals: Always use a matching ERTi-5 filler metal to maintain the joint’s integrity and mechanical properties.
- Shielding Gas: Titanium reacts instantly to oxygen and nitrogen when hot. You must use 100% high-purity argon gas shielding for the weld puddle, the cooling weld bead, and the backside of the joint to prevent contamination and embrittlement.
Heat Treatment Protocols
We utilize specific thermal cycles to dial in the mechanical properties needed for the final application:
- Mill Annealing: Held at 1300°F – 1450°F (704°C – 788°C) for 1 to 2 hours. This relieves internal stresses from aggressive machining or forming and ensures tight dimensional stability.
- Solution Treating and Aging (STA): To maximize overall strength, the material is heated to roughly 1750°F (954°C), rapidly water-quenched, and then aged at 1000°F (538°C) for several hours. This protocol locks in the exceptional strength needed for critical aerospace and defense components.

Frequently Asked Questions (FAQs)
Grade 5 Titanium vs. Ti-6Al-4V ELI
While Grade 5 Titanium is the standard workhorse for industrial and aerospace sectors, Ti-6Al-4V ELI (Extra Low Interstitial) features tighter limits on oxygen, carbon, and iron. This careful control over interstitial elements gives the ELI grade significantly higher ductility and better fracture toughness at low temperatures. We typically recommend the ELI grade for medical implants and highly critical aerospace components where maximum flaw tolerance is non-negotiable.
Is Ti-6AL-4V Magnetic?
No. The Ti-6AL-4V alloy is completely non-magnetic. This non-ferromagnetic property is a major reason why Ti64 material is heavily utilized in the medical field for MRI-safe surgical implants, as well as in electronic housings and subsea equipment where magnetic interference must be avoided.
Ti64 vs. Commercially Pure (CP) Titanium
Commercially Pure (CP) titanium offers incredible corrosion resistance and excellent formability, making it great for chemical processing. However, it lacks the heavy-duty strength required for structural applications. By alloying titanium with aluminum and vanadium, Ti64 achieves a massive increase in tensile and yield strength. It stands out as a highly reliable metal when evaluating the properties of high-temperature alloys, delivering a superior high strength-to-weight ratio metal profile compared to unalloyed CP titanium. If you need structural integrity under extreme stress, Ti64 is the clear choice.
