Titanium woven wire mesh in CP Gr1 / Gr2, with Pd-stabilized Gr7 for reducing-acid and chlor-alkali service. Opening 0.05–6.0 mm, wire Ø 0.025–2.0 mm, plain / twill / dutch weave. Supplied to ASTM E2016 with EN 10204 3.1 MTR; standard stock ships in 5–7 days with custom mesh-count in 4–6 weeks.
Honest Positioning
BOZE Metal is a sourcing and processing partner for titanium woven mesh, not a primary melter. The following scope clarifications are necessary for accurate technical and commercial alignment on electrochemical, filtration, and cathodic-protection mesh orders.
Sponge, VAR and EBM melting, wire-bar drawing, and wire production is not in our vertically integrated scope. We source wire and mesh-blank from upstream mills; our scope is weaving, surface conditioning, slitting, and quality verification.
Material specifications are applied "where applicable" per order. AS9100D governs our QMS, not every shipment classification. Confirm criticality class, specification (ASTM E2016, ISO 9044), and required documentation per RFQ.
We supply mesh to medical material specifications (ASTM F67, F136) where applicable. We are a material supplier and processor, not a finished medical device manufacturer; downstream device-level certification remains the device maker responsibility.
Engineering review and quotation timelines are confirmed at the RFQ stage based on the order complexity, alloy, mesh count, weave pattern, and downstream processing required. Standard stocked items typically receive a same-week response.
Standard stocked mesh counts are 4 through 325. Mesh counts above 325 (aperture below 45 micrometer) require specialized tooling and dedicated weaving campaigns; confirm feasibility and lead time at the RFQ stage.

Grade 2 (CP) and Pd-stabilized Grade 7 woven mesh is the standard substrate for chlor-alkali membrane cells, PEM electrolyzer current collectors, and mixed-metal-oxide (MMO) coated anodes. Bright-annealed and pickled surface is supplied; surface-conditioned roughness is available for catalytic coating adhesion.
Grade 2 (CP) plain and twill weave mesh is the workhorse for seawater and brackish-water filtration. Grade 12 (Ti-0.3Mo-0.8Ni) dutch-weave mesh is supplied for hot brine and seawater filtration in chlor-alkali feed circuits. Grade 2 expanded-and-woven mesh is the standard cathodic-protection anode for pipeline and marine structure protection.
Additional Applications
Four additional service environments where titanium woven mesh is the default specification, with the grade and weave that procurement teams typically call out.
PEM and alkaline water electrolysis current collector. Grade 2 plain weave with Pt / Ir / Ru coating substrates.
Current-collector mesh for advanced battery and supercapacitor cell designs. Gr.2 fine mesh is the workhorse specification.
Decorative and solar-shading woven mesh for marine and high-corrosion architectural facades. Gr.2 bright finish.
Sieving, sample filtration, and analytical support mesh. Gr.1 bright finish for inert laboratory service.
Production Workflow
From incoming wire stock verification through weaving, surface cleaning, NDT, slitting, and EN 10204 3.1 MTR issuance - six controlled stages with documentation checkpoints at each handoff.
Grade-certified titanium wire (matching the mesh wire diameter) is received with upstream-mill heat-lot, chemistry, and surface-state records. Lot is verified against ASTM E2016 and ISO 9044 before the weaving line starts.
Wire is straightened, stress-relieved, and lubricated for weaving. Warp wires are loaded onto a loom beam under controlled tension; shute wires are loaded into shuttles or rapier heads per the mesh count specification.
The loom weaves wire per the customer-specified pattern and mesh count. Plain weave is the workhorse for general filtration; twill weave for finer mesh counts above 200; dutch weave (plain or twill) for high-pressure filtration where mechanical strength is critical.
As-woven mesh is ultrasonic-cleaned to remove loom lubricant, then acid-pickled to remove the oxide scale from the heat-affected weaving zone. Bright anneal is available for the cleanest surface state.
100 percent visual inspection of every roll. Aperture and wire diameter are sampled per ASTM E2016 (10 measurements per square foot). Mesh count is verified with calibrated reticle; tensile test on the wire per ASTM E8.
Mesh is slit to customer-specified roll width, level-wound on cores, vacuum-sealed for medical / AM grades, and shipped with an EN 10204 3.1 MTR (chemistry, mechanical data, mesh count and aperture report) traceable to the originating heat.
Operating Boundaries
Three service-environment boundaries that drive alloy selection, surface finish, and weave-pattern class. Confirm these constraints at the RFQ stage.
Fine-mesh counts above 200 (opening below 75 micrometer) require laser-monitored looms and tighter aperture tolerance. Standard mill tolerance is plus or minus 10 percent; tight-tolerance mesh (plus or minus 5 percent) is available with a tooling surcharge. Confirm the tolerance class at the RFQ stage.
Bright annealed and pickled surface is required for chlor-alkali membrane, PEM, and biomedical service. As-woven mesh carries residual lubricant and oxide scale that must be removed before installation; specify surface conditioning at the RFQ stage.
Plain weave is the workhorse for low-pressure filtration. Twill weave supports higher flow and finer mesh count. Dutch weave (plain or twill) supports high-pressure filtration with finer absolute retention. Confirm the service pressure, flow rate, and absolute retention target before weave selection.

Coordinate Measuring Machines verify every critical dimension against GD&T to ±0.005 mm before any part ships.
Project-specific First Article Inspection Reports delivered for every new part number — engineered for fast PPAP / FAIR approval.
Material Test Reports (mill certificates) accompany every shipment for full source-to-component traceability.
Procurement and Lead Time
Stock availability, MOQ flexibility, and lead-time windows for titanium woven mesh. Final lead time is confirmed at the RFQ stage against the current upstream-mill schedule.
Weaving capacity in the 2 to 500 mesh-count range, wire 0.025-2.0 mm. Engineering samples of small panel sizes (about 0.5 m2) are feasible; production rolls of up to 30 m are standard. Specialty alloy and fine-mesh counts are scheduled against upstream wire campaigns.
Standard stocked mesh-count / grade combinations have no minimum order quantity for engineering sampling. Non-stock mesh count, custom weave pattern, and small-lot medical-grade mesh are scheduled against upstream-mill batches; MOQ is determined by the mill campaign and confirmed at the RFQ stage.
Standard stocked mesh items ship in 5-7 days. Non-standard mesh count, custom alloy, and fine-mesh wire run 4-6 weeks, driven by upstream-wire heat and weaving campaign. Engineering review and final quotation timing is confirmed at the RFQ stage.
Dimensional Comparison
Four procurement-relevant dimensions comparing titanium woven mesh (Gr.2 reference) against the conventional austenitic stainless and pure nickel mesh alternatives in seawater, electrochemical, and filtration service.
| Dimension | Titanium Mesh (Gr.2) | Austenitic SS Mesh (304 / 316L) | Nickel Mesh (Ni 200 / Monel) |
|---|---|---|---|
| Seawater / brine corrosion | Effectively immune to pitting and crevice corrosion in seawater and brine | Susceptible to pitting and crevice in chloride-bearing media | Susceptible to ammonia and sulfide attack |

| Biofouling in raw-water filtration | Smooth, oxide-passive surface; minimal marine-fouling adhesion | Rough surface; high biofouling rate | Susceptible to biofouling and biofouling-driven pitting |
| Life-cycle cost (LCC) | Higher initial investment, decades of service in seawater and reducing-acid media | Lower initial cost, frequent replacement in chloride service | Mid initial cost, replacement due to ammonia / sulfide attack |
