Nickel Wire Mesh Grades and Specifications
Nickel wire mesh is woven from commercially pure nickel wire, most commonly Nickel 200 or low-carbon Nickel 201. The grade alone does not define performance: mesh count, wire diameter, aperture, weave, temper, cut form, process medium, temperature, and verification route belong in the RFQ. For industrial woven wire cloth, ASTM E2016 and ISO 9044 provide useful terminology and tolerance references.
Nickel 200 (UNS N02200) or low-carbon Nickel 201 (UNS N02201); state the requested designation on the RFQ and purchase order.
Nickel 201 is the low-carbon option preferred for prolonged exposure above 315°C / 600°F; Nickel 200 is normally selected below that threshold when its other properties suit the duty.
Pure Nickel product entries currently list 40 mesh with 0.25 mm wire and 80 mesh with 0.12 mm wire. Confirm grade, availability, tolerances, and form before ordering.
Provide mesh count per linear inch, wire diameter, aperture, open area, and the acceptable tolerance. Mesh count alone does not define the opening.
Describe plain, twill, or Dutch weave as applicable, plus roll, sheet, disc, screen, framed part, edge condition, and dimensions to be quoted.
Request MTC documentation and agree the required composition and dimensional checks. Handheld XRF can support alloy screening but cannot directly measure carbon.
| Grade | Designation | Carbon limit | Selection guidance | |
|---|---|---|---|---|
| Nickel 200 | UNS N02200; W.Nr. 2.4060 / 2.4066 | 0.15% max | Commercially pure wrought nickel with useful resistance to reducing chemicals and caustic alkalies. Select only after checking the actual medium, contaminants, and operating temperature. | |
| Nickel 201 | UNS N02201; W.Nr. 2.4061 / 2.4068 | 0.02% max | Low-carbon counterpart to Nickel 200. Preferred where prolonged service exceeds 315°C / 600°F because lower carbon reduces graphitization risk. |
Current Pure Nickel Catalog Reference
These values come from the current Pure Nickel catalog product record. They are reference points, not a stock or lead-time promise; confirm the final grade, weave, dimensions, tolerances, and quantity in the RFQ.
| Mesh count | Wire diameter (mm) | Aperture (mm) | Open area | Listed weight (kg/m²) | |
|---|---|---|---|---|---|
| 40 mesh | 0.25 | 0.385 | 36.8% | 1.25 | |
| 80 mesh | 0.12 | 0.198 | 38.8% | 0.58 |
Nickel 200 vs 201: What Changes the RFQ
Start with process conditions, then select the grade. This is selection guidance from published alloy data, not a blanket material-compatibility approval.
| Decision point | Nickel 200 | Nickel 201 | RFQ action | |
|---|---|---|---|---|
| Continuous temperature | Normally limited to below 315°C / 600°F to avoid graphitization-related property loss. | Preferred above 315°C / 600°F because of its lower carbon content. | State normal and upset temperature, dwell time, and atmosphere. | |
| Caustic service | Often considered for caustic alkalies after evaluating concentration, temperature, and contaminants. | Also used in caustic service; select the low-carbon grade for elevated-temperature duty. | State caustic concentration, temperature, flow, chlorates, sulfur species, and cleaning cycle. | |
| Grade verification | Carbon limit is part of the grade definition. | Lower carbon limit distinguishes it from Nickel 200. | Request traceable MTC chemistry; do not rely on handheld XRF alone for a carbon-based distinction. |
Nickel Wire Mesh RFQ Checklist
Providing these fields lets the sourcing and factory teams evaluate a comparable requirement instead of quoting against an incomplete mesh count.
| Field | What to state | Why it matters | |
|---|---|---|---|
| Material | Nickel 200 / N02200, Nickel 201 / N02201, or another named nickel grade | Prevents a purity or carbon-content assumption. | |
| Geometry | Mesh count, wire diameter, aperture, open area, and tolerance | Defines screening performance and metal content together. | |
| Construction | Plain, twill, or Dutch weave; finished form and edge condition | Determines flow path, rigidity, fabricability, and finishing work. | |
| Process duty | Medium, concentration, contaminants, temperature, pressure, and cleaning chemistry | Nickel compatibility depends on the complete environment, not the material name alone. | |
| Acceptance evidence | MTC, dimensional checks, PMI scope, sample need, packing, quantity, destination, and required date | Aligns documentation, inspection route, logistics, and quotation basis. |
Specify the Construction, Not Just “Nickel Mesh”
The requested construction changes opening shape, thickness, flow behavior, surface profile, and fabrication route. State the desired weave or finished form rather than assuming that one mesh description fits every application.
Plain woven nickel mesh
Balanced one-over, one-under construction used when a square opening and straightforward mesh-count specification are appropriate. State wire diameter and aperture with the mesh count.
Twill woven nickel mesh
A two-over, two-under pattern that can support finer wire combinations. Define the required opening, wire, thickness, and handling needs rather than using weave name alone.
Dutch weave nickel cloth
A dense filtration construction with different warp and shute wire combinations. Specify retention requirement, flow direction, pressure differential, and cleaning regime for engineering review.
Cut mesh parts and screens
Sheets, discs, framed screens, and other finished forms require the fabric geometry plus final dimensions, edge condition, flatness expectation, and joining or mounting details.

Where Nickel Wire Mesh Can Be Evaluated
These are common industrial use scenarios, not a substitute for compatibility testing or a statement that every process is suitable. Confirm the actual fluid, atmosphere, contamination risk, temperature, pressure, and local requirements before release.
Chemical and alkali filtration
Woven nickel mesh can be evaluated for screens and filter media in reducing or caustic process environments, with concentration, temperature, chlorates, sulfur species, and flow conditions reviewed first.
Battery electrode support
A conductive woven nickel substrate can be evaluated for research or production electrode assemblies. Define electrochemistry, coating route, mesh geometry, current loading, and qualification tests in the RFQ.
Electrolysis and hydrogen equipment
Nickel mesh is commonly considered as a conductive electrode or support in alkaline electrochemical systems. Final selection requires process-specific electrochemical and corrosion validation.
Fine liquid and gas separation
Plain, twill, or Dutch woven cloth may be assessed where a controlled opening and nickel chemistry are required. Match aperture and weave to retention target, pressure drop, and cleaning method.
Electronic and vacuum components
The conductivity and low gas-content characteristics published for commercially pure nickel make mesh a candidate material for defined electronic or vacuum hardware; confirm cleanliness and specification needs.
Elevated-temperature screens
For long exposure above 315°C / 600°F, Nickel 201 is the relevant commercially pure nickel grade to evaluate. Account for atmosphere, sulfur compounds, load, creep, and joining method.
How to Select Nickel Wire Mesh
Treat nickel mesh as an engineered screen, not a generic commodity. Lock chemistry and process duty first, then define geometry, construction, finished form, and acceptance evidence.
Start from the process medium
State chemistry, concentration, oxidizers, sulfur-containing contaminants, temperature, pressure, flow, and cleaning cycle. Nickel is not a universal acid or oxidizer solution.
Choose Nickel 200 or 201 deliberately
Use the lower carbon Nickel 201 as the grade to evaluate for extended service above 315°C / 600°F. For lower-temperature duty, confirm whether Nickel 200 meets the required chemistry and documentation.
Define the opening mathematically
Aperture in mm is approximately 25.4 divided by mesh count minus wire diameter in mm. Verify the required aperture and open area instead of accepting mesh count alone.
Match weave to function
Plain weave is a useful starting point for square openings; twill and Dutch weaves solve different fine-filtration needs. Include flow direction and pressure conditions for dense cloth.
Qualify evidence before volume
Set the MTC, dimensional, sample, and PMI expectations in advance. For a 200-versus-201 distinction, include a carbon-sensitive chemistry verification method when required.
Five Nickel Mesh Mistakes That Create Rework
Most nickel mesh disputes begin with an incomplete material or process specification, not with the price line.
Ordering “pure nickel” without a grade
Nickel 200 and Nickel 201 differ materially in permitted carbon content and high-temperature selection. Use the UNS designation in the RFQ.
Treating mesh count as the whole specification
The same mesh count can use different wire diameters and deliver different apertures, open areas, weights, and pressure drops.
Assuming nickel handles every acid or oxidizer
Compatibility changes with concentration, temperature, aeration, impurities, and flow. Escalate oxidizing and sulfur-containing environments for application-specific review.
Selecting Nickel 200 for prolonged high-temperature duty by default
Published Nickel 200 data normally limits use below 315°C / 600°F; evaluate Nickel 201 for longer exposure above that range.
Using handheld XRF as the sole proof of Nickel 201
Handheld XRF cannot directly measure carbon, the key chemistry difference between 200 and 201. Pair screening with traceable MTC chemistry and a suitable method when carbon confirmation is critical.
Benefits and Boundaries of Nickel Wire Mesh
Commercially pure nickel combines useful conductivity, fabricability, and corrosion behavior in selected environments. The same facts also define where an application-specific review is necessary.
Conductive woven structure
Commercially pure nickel has high electrical and thermal conductivity relative to many nickel alloys, making a woven screen relevant to electrical and thermal design discussions.
Useful in reducing and caustic service
Published alloy data identifies strong performance in many reducing chemicals and caustic alkalies, but concentration, heat, chlorates, sulfur, and flow remain decisive.
A clear high-temperature grade decision
Nickel 201 gives buyers a low-carbon path to evaluate when service exceeds 315°C / 600°F for extended periods.
Controllable screen geometry
Wire diameter, mesh count, aperture, open area, and weave can be specified separately so filtration or support requirements do not collapse into one ambiguous label.
Specification-led sourcing support
WireMesh Sourcing’s existing process supports factory matching, dimensional inspection, handheld PMI alloy checks, MTC document coordination, and export packing planning against the agreed specification.
Not a universal corrosion guarantee
Oxidizing media, sulfur-bearing exposure, high temperature, stress, and contamination can change material behavior. Treat this page as a starting point for an engineering RFQ, not a compatibility warranty.
Use this workflow to align material selection, fabric geometry, inspection, and final packing before production begins.
Turn Process Data Into a Nickel Mesh RFQ
Document the duty
Provide the medium, concentration, contaminants, temperature range, pressure, flow direction, cleaning method, and any regulatory or process limits.
Fix grade and geometry
Name Nickel 200 or 201, then specify mesh count, wire diameter, aperture, open area, weave, finished form, dimensions, and edge condition.
Agree acceptance evidence
Set MTC, sample, dimensional, and PMI requirements before production. Add a carbon-sensitive chemistry route if the 200/201 distinction is critical.
Confirm packing and destination
State quantity, destination, required date, packing constraints, and handling requirements so the final quote is scoped against the actual export need.
Packing Is Set Against the Finished Specification
Packing is confirmed with the factory after the mesh form, dimensions, edge sensitivity, quantity, destination, and handling requirements are defined. Do not assume a stock-roll packing method for cut or framed mesh parts.
Protect the mesh geometry
Identify whether the order is a roll, sheet, disc, frame, or fabricated screen so handling and protection match the finished form.
Keep records with the shipment
State the MTC, inspection-photo, marking, and packing-record requirements with the order rather than adding them after production.
Plan the export route
Confirm destination, consignment grouping, and delivery constraints before packing is finalized. WireMesh Sourcing coordinates export-ready packing as part of its existing sourcing workflow.
Nickel Wire Mesh in Engineering Context
These illustrations show where buyers may evaluate nickel wire mesh. They are not customer projects, performance claims, or material-compatibility approvals.
Battery electrode support
A conductive woven nickel substrate can be assessed for an electrode assembly after the electrochemistry, coating process, current density, geometry, and validation plan are defined.
Caustic process filtration
Nickel mesh can be considered for selected alkaline filtration duties, subject to a full review of concentration, temperature, chlorates, sulfur species, flow, and clean-in-place chemistry.
Electrolysis test hardware
For alkaline electrochemical hardware, define mesh construction, electrical contact, coating, electrolyte, operating window, and qualification criteria before specifying a nickel grade.
Electronic and vacuum screens
Where a conductive, woven metallic screen is needed in electronic or vacuum equipment, specify cleanliness, mesh geometry, fabrication, and verification requirements alongside the grade.
