TC4 Titanium Wire for Additive Manufacturing | Ti-6Al-4V (Gr5) WAAM / LMD / DED Feedstock, VAR, MTC 3.1

Meta Description: TC4 (Ti-6Al-4V) wire for additive manufacturing from Baoji — WAAM/LMD/DED/EBAM feedstock, VAR double melt, Ø0.8–1.6mm precision spool, ±0.02–0.03mm, bright-clean, low interstitials, EN 10204 3.1 lot-traceable. Deposited properties quoted per process, not brochure minima.

Overview — AM Wire Is Not Welding Wire

If you quote a TC4 AM project with "ERTi-5 welding wire", QA will kick it back. Wire-fed additive manufacturing consumes metal differently:

• Welding wire = arc stability + clean bead
• AM feedstock wire = uninterrupted feed + zero surface carbon/oil + tight cast/helix + interstitial ceiling + lot-to-deposit traceability

A poriferous print rarely comes from "bad titanium" — it comes from oil residue, hydrogen pickup, diameter drift, or cross-lapped spool tangling the feeder at layer 40. We supply TC4 (Ti-6Al-4V, R56400) as additive feedstock: VAR double melt, bright-annealed, roller-die drawn, precision layer-wound, lot-closed. Annealed condition default; STA/hip-post per build procedure, not pre-shipped as "finished properties".

Why TC4 for Wire AM

• α+β workhorse: strength-to-weight ~2× 304SS at equal mass
• WAAM deposition 1–4 kg/h on meter-scale structures (spar, rib, housing, nozzle preform)
• LMD/DED: localized cladding, repair, hybrid CNC+print
• EBAM: large near-net aerospace forgings without powder handling
• Post-anneal recovers near-wrought ductility; STA available PO-stated

Rule: large, low-volume, high-buy-to-fly-ratio parts → wire AM beats billet CNC on scrap. Micro-resolution medical lattice → powder bed, not wire.

Process × Diameter Map (TC4)

Diameter tolerance: ≤1.5mm ±0.02mm typical; 1.6mm ±0.03mm class. Final tolerance written in PO.

Stock Scope (Honest)

Honest line: common 1.2/1.6mm D200 rotate on qualified heats. ELI / STA / EBAM core / custom wind → melt schedule quoted before PI. No "any spec same-day".

Interstitial Control — The Real AM Spec

MTC lists measured O/H/N/C — not "complies". That is what lets you correlate wire lot → deposit CTQ.

Feedstock Physical Spec (What Printers Actually Feel)

• Diameter tol: ±0.02mm (≤1.5mm) / ±0.03mm (1.6mm)
• Cast (coil set): controlled radius, no tight kinks
• Helix: minimal; straightness on straight-feed variant <2mm/m
• Layer wind: precision, edge-controlled, no cross-lap / no overlap
• Surface: Kodak gray ≤Grade 3 class cleanliness; no oxide scale, no drawing lube
• EdDY/UT on PO for >3mm; visual + dia-scan 100% on AM spool lots

Deposited Properties — Quoted Per Process, Not Brochure

Numbers are process-referenced ranges from WAAM/LMD practice, not a guarantee on your machine. Final deposit properties = your parameter window + post-heat + our lot MTC correlated together.

Gas & Process Notes (Printer-side)

• Shielding: Ar ≥99.99% (WAAM/LMD), chamber vacuum for EBAM
• Interpass 150–300°C controls residual stress (WAAM reference)
• No oil, no glove print on wire — open spool at clean feeder only
• Vacuum-foil + desiccant pack; reseal half-used spool
• Density target ≥99.5% with correct purge + power — wire can't fix a leaky chamber

Traceability Chain

• VAR double melt (triple on request) — ingot pedigree on MTC
• Lot-to-ingot heat No. across spool → deposit coupon
• EN 10204 3.1, mill-authorized IR: chemistry (interstitials called out) + tensile + cast/helix report
• 3.2 (SGS/BV/TÜV) witness PO-fronted, not back-signed
• Gr23 ELI AM = separate PO, F136/ISO 5832-3 chain, never mixed with industrial TC4

Packaging

• D200/D300 plastic spool, vacuum foil + desiccant + aluminium barrier
• "ARGON-CLEAN / NO OIL / DRY" outer label
• Plywood case / antistatic carton, spool face protected
• Pre-ship photo: spool face + lot tag + seal

FAQ — TC4 Wire for Additive Manufacturing

Q1: Can I use ERTi-5 welding wire for WAAM?
A: Technically feedable, but AM feedstock needs tighter cast/helix, lower surface carbon, and lot-to-deposit traceability. We supply TC4 as AM-grade, not relabeled MIG wire.

Q2: Best diameter for LMD?
A: 1.2mm is the mainstream laser-wire size; 0.8–1.0mm for fine-bead. Match to laser spot + powder-free nozzle, not "thinner = better".

Q3: Does annealed wire print at 895 MPa?
A: No. Base-wire UTS is annealed-minimum. As-built deposit runs ~900–950 MPa, rises to ~950–1000 MPa after anneal, depending on your heat input. We correlate lot MTC + your WPQ.

Q4: STA from stock?
A: No. Annealed default. STA/hip done per build procedure + PO, with re-MTC. Never pre-ship "print-ready STA properties".

Q5: Porosity in print — wire fault?
A: Often not. Leaky chamber, bad argon dewpoint, oil on guide tube cause it. Wire must be clean; process must be clean. We ship argon-sealed, you keep it sealed.

Q6: Gr23 ELI for AM?
A: Yes for fracture-critical / medical-adjacent. Lower O (≤0.13%), better fatigue, separate PO + F136 chain.

Q7: Spool tangling?
A: Precision layer-wind to feeder type (push/pull/dual). State feeder model — we wind, not just load.

Q8: UT on wire?
A: Eddy + dia-scan 100% on AM lots; volumetric UT on >3mm per PO. Acceptance threshold in contract, not "zero defect".

Q9: EBAM supply?
A: 1.2–2.0mm core/spool PO-fronted; chamber-feed pack agreed before dispatch.

Q10: Lead time?
A: 1.2/1.6mm D200 on qualified heats → same-week after PO+lots confirmed. ELI/STA/custom wind → melt schedule quoted before PI.
