6Al4V ELI Titanium Wire for Precision Components

6Al4V ELI titanium wire is commonly specified as Grade 23 Ti-6Al-4V ELI wire. The ELI grade is used when the buyer's drawing or specification requires extra-low interstitial chemistry compared with standard Grade 5 titanium alloy. It may be used for medical-related components, aerospace-related parts, precision pins, springs, fasteners, small machined parts and drawing-based wire components.

Wire requirements depend on grade, diameter, tolerance, surface condition, delivery form and downstream process. The RFQ should state whether the wire is needed as coil, spool, straightened wire or cut lengths.

Grade and Standard

Material: Grade 23 titanium / Ti-6Al-4V ELI.
Possible references: ASTM B863 for titanium wire when specified, ASTM F136 when the buyer requires implant-related chemistry, or customer specification.
Forms: coiled wire, spooled wire, straightened wire or cut-to-length wire.
Surface condition: bright, polished, pickled or project-specified finish.

Size and Tolerance

RFQs should include wire diameter, diameter tolerance, coil weight or cut length, straightness, surface finish and quantity. If the wire will be formed, welded, ground, machined or used in a medical-related device, provide the drawing and acceptance requirement.

Wire Form and Delivery-Condition Envelope

Beiyu's June 2026 product brochure separates the titanium wire program by supply form. The third column adds the length or packing field that a Grade 23 RFQ should state.

Supply form	Diameter range	Length or packing field
Straight wire	0.8 to 6.0 mm	Length to 6000 mm
Coil wire	0.8 to 12 mm	State coil weight and winding requirement
Spool wire	0.01 to 6.35 mm	State spool size and winding requirement

Where a Chinese-route order uses the delivery-condition codes, R means hot worked, M annealed and Y cold worked. These are Chinese-order condition codes; they do not replace the condition or acceptance wording required by ASTM B863, ASTM F136, AWS A5.16 or the drawing.

These figures are a capability envelope, not stock availability or a promise that every Grade 23 diameter, form, condition, tolerance and surface combination is available. Beiyu confirms the ordered combination at quotation. Medical or welding-filler work must also identify the governing standard, surface, inspection and certificate scope.

Applications

6Al4V ELI titanium wire may be used for springs, pins, fastener blanks, medical-related components, aerospace-related small parts, precision wire forms and custom industrial assemblies. Final suitability depends on the buyer's design, quality system and material specification.

Inspection and Documentation

Buyers may request mill test certificate, heat number traceability, chemical composition, mechanical properties, dimensional inspection and EN10204 3.1 documentation. Surface inspection, straightness inspection or third-party inspection should be stated before quotation when required.

Ti-6Al-4V ELI Wire Specification Snapshot

Alloy / grade	Ti-6Al-4V ELI, Grade 23 (UNS R56407 to ASTM B863; UNS R56401 to ASTM F136).
Specification	ASTM B863 for wire; ASTM F136 where the order is medical-chain and the purchase specification cites it.
Diameter	Common RFQ range around 0.5-6.0 mm, in straight lengths or spools, confirmed by form and condition.
Condition / surface	Annealed or cold worked by order; pickled or bright surface.
Use	Precision components, springs and medical-related device stock when the correct specification is stated.
Certificate	EN 10204 3.1 MTC with full interstitial chemistry; single-heat traceability by order scope.

State the certificate standard, B863 or F136, plus diameter, form, condition and quantity. The ELI chemistry is the point of this wire, so the interstitial reporting line matters.

Packing and RFQ Checklist

Titanium wire should be packed to prevent scratches, bending, tangling and heat-number mix-up. Send grade, standard, diameter, tolerance, delivery form, quantity, surface condition, documents and destination country for quotation.

FAQ

What does ELI mean in 6Al4V ELI wire?

ELI means extra-low interstitial. It refers to tighter chemistry control required by certain specifications.

Can this wire be supplied straightened?

Straightened or cut-to-length wire can be reviewed when the RFQ includes diameter, length, tolerance, straightness and quantity.

Which standard applies to titanium wire?

ASTM B863 is commonly used for titanium wire when specified by the buyer. Other standards may apply depending on application.

Procurement Notes for Titanium Wire

Wire orders should define delivery form early. Coil wire, spool wire, straightened wire and cut lengths have different packing and inspection requirements. If the wire will be fed through automatic equipment, specify coil weight, winding condition, surface finish and diameter tolerance. If it will be used for formed parts, include bend or forming requirements.

For medical-related or aerospace-related components, buyers should identify whether the order is for sample trials, validation or repeat production. Heat traceability, labelling and document packages should be planned before shipment.

RFQ Details for Ti-6Al-4V ELI Wire

For Ti-6Al-4V ELI wire quotations, buyers should specify diameter, coil or spool form, annealed or straightened condition, surface finish, applicable ASTM F136 or ASTM B863 requirement, and whether full heat traceability is needed. For medical and precision applications, the RFQ should also include tensile requirement, straightness, cleaning requirement, and packaging method to prevent surface contamination during export transit.

Specification detail with sources

Grade 23 is Grade 5 with the interstitials pulled down, and the difference is visible in the limits rather than in the alloy name. Against Grade 5 at 0.20 percent oxygen maximum and 0.015 percent hydrogen maximum, Grade 23 carries 0.13 percent oxygen maximum and 0.0125 percent hydrogen maximum, with iron reduced to 0.25 percent maximum, while the aluminium and vanadium ranges stay close at 5.5 to 6.5 percent and 3.5 to 4.5 percent (ASTM B348, chemical requirements). Extra low interstitial is a set of tighter numbers on the same elements, not a separate alloy system.

Because the margin is narrower, the method behind each figure matters more. ASTM B348 references ASTM E1409 for oxygen and nitrogen, ASTM E1447 for hydrogen and ASTM E1941 for carbon, and requires rounding to ASTM E29 before a result is compared to a limit (ASTM B348, referenced documents and test methods). Those limits are heat analysis limits taken at the melt, and a later product analysis carries its own tolerance that exists to cover variation between laboratories rather than to widen the grade. The UNS number also depends on the standard the order names: ASTM B series product specifications carry R56407 for Grade 23, while R56401 belongs to the implant specification ASTM F136. Beiyu Titanium supplies wire with an EN 10204 3.1 mill test certificate carrying heat number traceability, with the reporting scope set by the order.
