Tantalum Mesh (Ta Mesh) Selection Notes

Tantalum Mesh (Ta Mesh) belongs to the tantalum products range and is selected for corrosion resistance, biocompatibility and high-temperature stability. It is commonly used in project-specific assemblies, prototypes, replacement parts and drawing-based ceramic components as well as chemical processing, medical devices, electronics, vacuum systems and high-temperature components. When requesting a quote, confirm drawings, dimensions, tolerances, material grade, surface finish, quantity and working environment.

Tantalum Mesh Specifications

Mesh dimensions and manufacturability depend on mesh type, material thickness or wire diameter, opening geometry, overall dimensions, and required tolerances.

Woven Tantalum Wire Mesh

Woven tantalum mesh is manufactured from tantalum wire using controlled weaving patterns.

Available weave configurations include:

• Plain weave
• Twill weave
• Custom configurations upon request

Woven tantalum wire mesh is suitable for applications requiring controlled openings, filtration, screening, separation, vacuum components, and specialized chemical or high-temperature service.

When requesting woven mesh, specify the wire diameter, opening size or mesh count, weave pattern, overall width and length, and quantity.

Expanded Tantalum Mesh

Expanded tantalum mesh is produced from tantalum sheet by creating and expanding a controlled pattern of openings without conventional wire weaving.

Custom parameters can include:

• Opening length
• Opening width
• Strand or stem width
• Material thickness
• Overall width
• Overall length
• Opening geometry

A typical custom opening may be specified by the long and short diagonals of the diamond pattern.

Expanded tantalum mesh is suitable for applications requiring an open tantalum structure combined with mechanical integrity and corrosion-resistant material performance.

Tantalum Mesh FAQ

What types of tantalum mesh are available?

Heeger Materials supplies both woven tantalum wire mesh and expanded tantalum mesh. Woven mesh is available in plain and twill weave configurations, while expanded mesh can be customized according to opening geometry, material thickness, and stem width.

What tantalum grades are available for mesh?

Tantalum mesh is available in R05200 and R05400. Please specify the required material grade and any chemical composition or documentation requirements when requesting a quotation.

Can tantalum mesh opening sizes be customized?

Yes. Opening size, wire diameter, mesh count, material thickness, stem width, overall dimensions, and other parameters can be customized according to the mesh type and manufacturing requirements.

What is the difference between woven and expanded tantalum mesh?

Woven tantalum mesh is produced by weaving tantalum wires, while expanded tantalum mesh is produced from tantalum sheet to create an open one-piece structure. The appropriate type depends on opening requirements, geometry, mechanical requirements, and application.

What information should I provide for a quotation?

Please provide the mesh type, tantalum grade, opening size or mesh count, wire diameter or material thickness, stem width if applicable, overall dimensions, tolerances, form, and quantity. For custom mesh geometries, attach a technical drawing.
