Nickel Fiber Felt Specifications
| Item | Available specification |
|---|---|
| Material grades | Nickel 200, Nickel 201, N4, N6 and N8. Specify the required grade and chemical composition requirements. |
| Thickness options | 0.1, 0.25, 0.4, 0.6, 0.8 and 1 mm. Confirm the selected thickness and its tolerance for the order. |
| Porosity range | 50%–85%. Specify the target porosity and agreed measurement method; the range does not describe every thickness/grade combination. |
| Maximum sheet size | 1500 × 1800 mm. Cutting dimensions and tolerances follow the order drawing. |
| Cut sizes | Examples include 100 × 100, 200 × 200, 200 × 300 and 500 × 500 mm; other dimensions can be specified. |
| Supply forms | Full sheets, strips, discs, custom cut shapes and formed parts are available for long-term supply. |
| Mesh-supported options | Nickel fiber felt with mesh on one side or both sides. Specify the support mesh material, structure and joining requirements. |
| Surface condition | Manufactured according to the drawing requirements. |
Thickness, porosity, area mass and the compressed condition should be considered together. A porosity value alone does not establish permeability, electrical contact resistance or electrochemical performance. Specify the material grade and any required composition documentation.
Supply Forms and Mesh Support
Choose full sheets for subsequent processing, or specify strips, discs, shaped blanks or formed components to fit the assembly. Provide the drawing, dimensions, tolerances, edge requirements and any handling restrictions.
Single-sided and double-sided mesh-supported nickel felt are available. The mesh and felt serve different structural functions. Specify the mesh grade and geometry, the required orientation and the finished thickness, especially where compression or contact with another component matters.
Selecting Thickness, Porosity and Compression
- Material and environment: specify the nickel grade, electrolyte composition, temperature and electrode potential or position where relevant.
- Transport: consider liquid wetting and gas removal together with thickness and pore structure. Higher porosity alone does not determine better performance.
- Electrical contact: define the installed compression and mating surfaces when contact resistance is important.
- Mechanical fit: provide the free thickness, installed gap, dimensional tolerance and support requirements.
- Surface condition: agree cleanliness, handling and any downstream processing requirements.
Inspection and Order Requirements
Define the acceptance plan before manufacture. It can cover dimensions, thickness, material documentation, porosity and visual condition. If area mass, permeability, resistance or another functional property is required, agree the test method, conditions and acceptance limits for that order.
For mesh-supported parts, identify the mesh material and orientation and any requirements for the finished composite. Test and compare samples under consistent compression and operating conditions where these affect the result.
Applications in Alkaline and AEM Water Electrolysis
Nickel fiber felt can be evaluated as a porous electrode material in alkaline water electrolysis (AWE), and as a porous transport layer or conductive electrode support in anion exchange membrane water electrolysis (AEMWE). The intended role depends on the cell architecture, electrode side, electrolyte and catalyst arrangement.
It can also serve as a substrate for subsequent catalyst loading. Specify the substrate requirements separately from the catalyst composition and electrode activation procedure. Uncoated felt is a starting material; its electrochemical performance depends on the complete electrode and cell design.
Nickel Fiber Felt FAQs
Is nickel fiber felt the same as nickel foam or woven nickel mesh?
No. Fiber felt contains a sintered network of nickel fibers. Nickel foam has a cellular structure, while woven nickel mesh is made from interlaced wires. Their pore structures and mechanical behavior differ; select them for the specific assembly rather than assuming one is always superior.
Which nickel grades are available?
Nickel 200, Nickel 201, N4, N6 and N8 are available. State the required grade and composition requirements on the order.
Can nickel felt be supplied with support mesh?
Yes. Both single-sided and double-sided mesh-supported nickel fiber felt are available. Specify the mesh material, construction and finished dimensions.
What shapes and maximum sheet size can be supplied?
Full sheets up to 1500 × 1800 mm, strips, discs, custom cut shapes and formed parts can be supplied. Finished dimensions and tolerances follow the approved drawing.
Does porosity above 80% apply to every grade?
No. The available porosity range is 50%–85%. Specify the target for the selected thickness and construction; porosity alone does not guarantee transport or electrochemical performance.
Send Your Drawing, Specification or Sample Photos
Send the drawing or existing specification you have, together with the quantity and the parts you need. Sample photos and main dimensions are a useful starting point when a drawing is unavailable.
If you are still defining the product, briefly describe its intended use. We will clarify the additional manufacturing and inspection details with you.
