Tantalum mesh for corrosion-focused designs
Tantalum woven wire mesh is made by interlacing tantalum wires to form a metal cloth. It is considered for filtration, support and electrode components where the process environment makes material selection important.
Tantalum’s protective surface oxide gives it resistance to many corrosive media. The right mesh combines chemical compatibility with an opening, wire size and structure suited to the job.
Custom tantalum woven-mesh specification guide
Custom mesh specifications available. Use the combinations below as starting points, or send your drawing and application requirements.
| Mesh count / in | Wire diameter (mm) | Calculated nominal opening (mm) | Weave |
|---|---|---|---|
| 8 | 0.508 | 2.667 | Plain |
| 14 | 0.4064 | 1.4079 | Plain |
| 30 | 0.0762 | 0.7705 | Plain |
| 35 | 0.1981 | 0.5276 | Twill |
| 50 | 0.0762 | 0.4318 | Plain |
| 80 | 0.0762 | 0.2413 | Plain |
| 100 | 0.0762 | 0.1778 | Twill |
Square-opening woven mesh geometry is calculated from mesh count and nominal wire diameter. Final grade, weave, tolerances and dimensions are confirmed with your quotation.
Calculated nominal opening = 25.4 ÷ mesh count − wire diameter (mm), rounded to 0.0001 mm where needed. These design values are not inspection results or manufacturing tolerances.
Plain and twill examples are labelled by row. Dutch-weave requests use separate warp/weft and filtration requirements, not this square-opening calculation.
Specify your custom tantalum mesh
Start with the information you have: mesh or opening, finished size and quantity. A drawing, reference sample or short application description is also welcome.
| Custom requirement | Details to include |
|---|---|
| Material requirement | Specify the tantalum grade, composition or purity requirement and any material documents needed. |
| Weave selection | Plain or twill for square-opening designs; Dutch weave for a separately specified filtration structure. The table above identifies its plain and twill examples. |
| Mesh and wire | Choose a starting combination above, give a target opening, or provide both warp and weft counts and wire diameters for a Dutch-weave request. |
| Filtration requirement | For Dutch weave, state the filtration target and process fluid. A square-opening calculation is not a Dutch-weave filtration rating. |
| Finished dimensions | Width × length, piece or roll format, quantity, and any cut-edge or component drawing requirements. |
| Service and tolerances | Process medium, concentration and temperature; specify any critical dimensional tolerances or mechanical loading. |
You do not need to complete every technical detail before requesting a quote.
Applications and material selection
Potential uses include chemical-process screens, filter-support layers and mesh components for electrical or vacuum equipment. Suitability depends on the specific service conditions.
For chemical service, consider the full mixture and operating temperature. Hydrofluoric acid, fluoride-containing acidic solutions and strong alkalis can attack tantalum; it should not be treated as universally corrosion-resistant.
- Filtration and separation where material compatibility is a priority.
- Support mesh within a process or laboratory assembly.
- Electrode or vacuum-equipment components selected for a defined operating environment.
Frequently asked questions
Is tantalum mesh resistant to every acid?
No. Tantalum resists many corrosive media, but hydrofluoric acid and some fluoride-containing acidic solutions can attack it. Chemical concentration, mixtures and temperature all matter when selecting the material.
Is mesh count the same as opening size?
No. Mesh count describes the number of mesh openings per inch, while opening size also depends on wire diameter and weave. For Dutch weave, use the specified filtration characteristics rather than assuming a square opening.
Can I ask for a quote without a complete mesh specification?
Yes. Send your application, an existing sample description or a drawing. Include the dimensions and quantity if you know them; the remaining details can be discussed.
What if my project needs material documentation?
Mention the composition information, inspection records or other documents your project requires. The available documentation should be confirmed with the quotation.
