Fine Titanium Wire for Medical Mesh | ASTM F67 Gr1/Gr2 & F136 Gr23 ELI, 0.05–0.5mm, Electropolished, Lot-Traceable

Meta Description: Fine titanium wire for medical mesh from Baoji — ASTM F67 Gr1/Gr2 (CP) and F136 Gr23 ELI, Ø0.05–0.5mm, ±0.002mm tolerance, bright/electropolished, ultrasonic-clean, lot-traceable MTR. For precision weave, Dutch weave, braid-reinforced tubing, implant-grade mesh. Medical chain isolated from industrial stock.

Overview — Mesh Wire Is a Weaving Problem, Not a Welding Problem

Medical mesh lives or dies on wire consistency, not on a "titanium" label. A 0.1mm wire that drifts ±0.01mm will show up as:

• uneven aperture
• local necking → broken warp during weave
• elliptical cross-section → poor node closure in Dutch weave
• surface particles → biofilm risk in implant use

We supply fine titanium wire for medical mesh in two clean chains:

• ASTM F67 — unalloyed CP titanium (Gr1/Gr2), max ductility, corrosion passive film, non-load-bearing mesh / filtration / dental / soft-tissue containment
• ASTM F136 — Ti-6Al-4V ELI (Gr23), high strength + fracture toughness, load-bearing implant mesh, orthopedic containment, cranial/MaxFax structures

Industrial B863 Gr1 is NOT shipped as F67 unless the PO names F67 + medical clean chain. No silent upgrade, no silent downgrade.

Grade Selection for Mesh

Rule: non-implant / external-contact filtration → F67 Gr1. Load-bearing implant → F136 Gr23, with device master-file traceability.

Diameter & Tolerance (The Real Mesh Spec)

Multi-pass diamond-die drawing; roundness checked per lot. Elliptical wire rejected before spooling — it is the #1 cause of aperture drift in fine mesh.

Surface & Cleanliness

• Bright annealed → pickled → ultrasonic clean (particle residue controlled)
• Electropolish option: Ra ≤0.2 μm (implatable-surface grade)
• No drawing lube, no graphite, no glove-oil transfer
• Cleanroom-pack optional: ISO 11607-1 peel pouch + tyvek + desiccant
• Passivation per ASTM F86 / ISO 10993 preparation on request

Surface is not cosmetic. For mesh in body-fluid contact, Ra and particulate load drive cytocompatibility far more than the brochure "99.5% Ti" line.

Mechanical Reference (Annealed)

Values per ASTM F67 / F136 annealed min. Fine-wire measured values reported on MTR per lot; spring-temper variants quoted PO-stated.[9](@ref)

Weave Compatibility

• Plain weave: 0.05–0.15mm, stable tension, low open-area loss
• Twill weave: 0.15–0.30mm, higher mesh count, smoother surface
• Dutch weave (plain/twill): 0.05–0.12mm warp, tight filtration rating
• Braided sleeve / catheter reinforcement: level-wound spool, zero tangle

Tell us weave type + mesh count + warp/weft diameter — we match cast/helix so the warping machine does not fight the wire.

Traceability & Compliance

• Melt lot → rod → drawn wire → spool, one heat No.
• MTR (EN 10204 3.1 equivalent, mill-authorized): chemistry (O/H/N/C), tensile, diameter scan
• ASTM F67 / F136 cited on cert line — not "medical-grade" vague stamp
• ISO 13485-chain production reviewed on request; GMP-clean pack PO-stated
• 3.2 (SGS/BV/TÜV) witness PO-fronted
• F67 and F136 NEVER share a spool line with industrial B863 stock

Packaging

• Level-wound plastic spool (DIN 125 / D200 custom)
• Vacuum foil + desiccant + tyvek barrier for clean-pack
• Peel-pouch (ISO 11607) for implant-chain lots
• Lot tag: grade + standard + Ø + heat + clean-chain ID
• Pre-ship photo: spool face + seal + tag

Stock Honesty

No "all micron sizes same-day". Medical chain = scheduled, not rushed.

FAQ — Fine Titanium Wire for Medical Mesh

Q1: Can industrial Gr1 replace F67 for mesh?
A: Chemically close, but not document-equivalent. Implant/device filing needs F67 on the cert line + medical clean chain. We keep the two chains separate.

Q2: Smallest diameter you draw?
A: 0.05mm on medical ELI/drawing chain; sub-0.10mm quoted with draw schedule + yield loss disclosed.

Q3: Electropolish necessary?
A: For implant-surface contact, yes — Ra ≤0.2μm reduces particulate adhesion. External filtration can run bright-pickled.

Q4: Will it break on the loom?
A: Roundness + cast control is what prevents warp breakage. We reject elliptical lots before spooling, not after your loom stalls.

Q5: Gr23 too stiff for fine mesh?
A: Stiffer than Gr1, yes. 0.15–0.30mm Gr23 weaves well with correct tension; below 0.10mm Gr1/F67 is the safer draw.

Q6: MTR real interstitials?
A: Yes — O/H/N/C measured per lot, F136 O≤0.13%.

Q7: Cleanroom pack?
A: ISO 11607 peel pouch + tyvek + desiccant, PO-stated. Not default on industrial orders.

Q8: Dutch weave warp/weft different Ø?
A: Common. Send warp + weft diameters; we supply two spools, one heat family, separate tags.

Q9: Biocompatibility test (ISO 10993)?
A: Material meets F67/F136 chemistry + MTR; full device-biocompatibility dossier is customer-device responsibility. We supply material-level data pack to support it.

Q10: Lead time?
A: F67 common Ø → lot-confirmed, same working week. F136 ELI / sub-0.10mm / electropolish → melt+clean schedule quoted before PI.
