Standards, UNS & Manufacturing Route Identity
Grade 23 / Ti-6Al-4V ELI is not released for purchase by alloy name or UNS number alone. Product form, governing specification, revision, material condition and manufacturing route determine the actual material identity used for an order.
Route Principle
Grade 23 identity follows the governing specification, product form and condition — not one universal UNS label. General ASTM Grade 23 wrought products commonly use UNS R56407. ASTM F136 surgical-implant material uses UNS R56401. Aerospace ELI identity is further defined by the exact AMS product form and material condition.

Check Size & AvailabilityGrade 23 Titanium · ELI Material Identity
What ELI Really Means
Ti-6Al-4V ELI remains an alpha-beta titanium alloy based on aluminum and vanadium. The ELI route adds tighter control of oxygen and other interstitial or residual elements, so material identity should be read through the governing specification and actual heat analysis, not through the alloy name alone.
Grade 23 is still Ti-6Al-4V. Its engineering distinction comes from tighter control of interstitial and residual elements, particularly oxygen, rather than from a claim of universally higher strength.
Ti-6Al-4V remains the alloy system.
Grade 23 belongs to the same alpha-beta titanium alloy family as conventional Ti-6Al-4V. Aluminum and vanadium remain the primary alloying elements; ELI does not create a new base alloy.
- Al 5.5-6.5% reference range
- V 3.5-4.5% reference range
- Ti balance
Oxygen is central, but ELI control is broader than one element.
Oxygen, iron, carbon, nitrogen and hydrogen are controlled through the applicable material route. Lower permitted interstitial content is part of what distinguishes Grade 23 ELI from standard Ti-6Al-4V material.
The purchase value is damage tolerance, not a stronger marketing label.
Ductility
Lower interstitial control can support a different
strength-ductility balance from standard Ti-6Al-4V.
Damage Tolerance
ELI producer data emphasize fracture toughness and
fatigue crack-growth behavior for demanding applications.
Low Temperature
ELI is also selected where low-temperature or cryogenic
mechanical behavior forms part of the engineering review.

Microstructure
Alpha + beta is the alloy family; the actual structure comes from processing history.
Ti-6Al-4V properties are strongly influenced by microstructure, while microstructure is created by thermomechanical history and heat-treatment condition.
Evidence Rule
Where metallography is required, use evidence from the actual material, section and condition rather than a decorative “standard Grade 23 microstructure” image.
Grade 23 Titanium · Material Selection
Grade 23 vs Grade 5
Grade 5 and Grade 23 belong to the same Ti-6Al-4V alpha-beta alloy family. The Grade 23 ELI route uses tighter control of key interstitial and residual elements and is selected through its governing specification, not as a universal performance upgrade over Grade 5.
Common Alloy Family
Both routes are Ti-6Al-4V. The selection changes when chemistry control, damage tolerance, low-temperature behavior or a specific medical / aerospace specification becomes part of the requirement.
Standard Ti-6Al-4V Route
Grade 5
Ti-6Al-4V · standard interstitial levelGrade 5 is the conventional Ti-6Al-4V route used across a broad range of structural, aerospace and industrial requirements. Its acceptance criteria still depend on the product specification, form and condition selected for the order.

Extra Low Interstitial Route
Grade 23 ELI
Ti-6Al-4V ELI · tighter chemistry controlGrade 23 remains Ti-6Al-4V, but the ELI route applies tighter control to key interstitial and residual elements. The purpose is not to create a universally stronger alloy; the route is associated with material specifications that place greater emphasis on toughness, damage tolerance or low-temperature performance.

Selection Intent
Use the Grade 23 ELI route when the governing medical, aerospace, fracture-critical, low-temperature or customer specification explicitly requires ELI-controlled Ti-6Al-4V.
Selection Rule
Do not reclassify material by test results alone. A Grade 5 heat that happens to show low oxygen, similar strength or favorable toughness does not automatically become Grade 23. Material identity follows the governing specification, required chemistry, condition, testing and traceability route.

Aerospace, Fracture-Critical & Low-Temperature Routes
Aerospace Ti-6Al-4V ELI should be purchased by the exact AMS product form and condition. Annealed, beta-annealed, duplex-annealed and welding-filler routes serve different engineering requirements and should not be treated as interchangeable.
Aerospace Selection Principle
In aerospace ELI material, condition is part of the material identity.

AMS4956J covers Ti-6Al-4V ELI wire for welding filler metal. It should not be treated as interchangeable with ordinary Grade 23 material wire or with AMS4930 long-product material.
ELI producer literature also associates the alloy with improved damage tolerance and better mechanical behavior at cryogenic temperatures. Actual aerospace acceptance still follows the specified AMS route, product form, condition and required test evidence.
Grade 23 Titanium · Precision Fabrication
Forming, Welding & Machining Ti-6Al-4V ELI
Grade 23 fabrication is controlled through process discipline rather than a claim of easy machinability. Heat removal, rigid machining, clean tooling and surfaces, qualified welding protection and the correct material or filler-wire identity all affect the finished result.
Precision Machining
Titanium’s low thermal conductivity concentrates heat near the cutting zone, while its low modulus increases the importance of machine, fixture and workpiece rigidity.
Use rigid setups, sharp tooling, controlled cutting action and effective coolant delivery. Avoid rubbing or tool dwell while the tool and work remain in moving contact.
GTAW and other qualified fusion-welding routes require clean joints and filler, inert primary shielding and, where required, trailing and backside protection while the titanium remains reactive.
Forming response depends on material condition, section, geometry, tooling and springback. Any subsequent heat treatment should follow the governing specification or qualified process.

Grade 23 RFQ Desk & Buyer FAQ
A quote-ready Grade 23 request starts with material identity and ends with the actual delivery and quality requirement. Send the governing specification, revision, product form, dimensions, quantity, condition and inspection scope so the supply route can be confirmed without assumptions.
Buyer FAQ
Six questions that directly affect purchase definition
01 Is Grade 23 always UNS R56401?
No. General ASTM Grade 23 wrought product routes commonly use UNS R56407, while ASTM F136 medical-material requirements use UNS R56401. The governing specification determines the material identity used for the order.
02 What is the difference between Grade 23 and Grade 5?
Both belong to the Ti-6Al-4V alpha-beta alloy family. Grade 23 ELI uses tighter control of key interstitial and residual elements and is purchased where the applicable specification calls for an ELI-controlled material route. It should not be treated as a universal higher-strength replacement for Grade 5.
03 Does Grade 23 automatically comply with ASTM F136?
No. ASTM F136 is a specific wrought annealed Ti-6Al-4V ELI medical-material specification with its own product forms, chemistry, mechanical and metallurgical requirements. “Grade 23” alone does not establish F136 compliance.
04 Can you confirm stock or production availability?
Availability is confirmed against the actual product form, specification, dimensions, condition, quantity and required processing. Stock, production, made-to-order and qualified-source supply are treated as different commercial routes.
05 What affects Grade 23 price, MOQ and lead time?
Product form, dimensions, tolerance, quantity, material condition, surface, machining or secondary processing, testing, documentation and destination can all affect the commercial route. Price, MOQ and lead time are therefore confirmed against the actual RFQ rather than one fixed value.
06 What inspection and documentation can be specified?
Define the required chemistry, mechanical testing, metallurgical examination or NDT where applicable, together with MTC requirements. EN 10204 3.1 documentation and third-party inspection should be specified or agreed when required for the order.
Grade 23 / Ti-6Al-4V ELI
