Open-Cell Nickel Foam 20 PPI 200×200×10 mm ATOMFAIR®

Laboratory Open-Cell Nickel Foam, 20 PPI, 200 × 200 × 10 mm, 1/5 pcs

Research-grade laboratory product

Product Overview

Open-cell nickel foam with 20 PPI is a lightweight, electrically conductive porous-metal sheet built around a continuous three-dimensional nickel skeleton. In this 200 × 200 × 10 mm format, the approximately 1.27 mm nominal pore pitch creates a regular open network with extensive internal surface exposure, allowing gases, liquids and electrochemical reactants to move through the material instead of remaining confined to the outer faces.

The interconnected framework gives the sheet a useful balance of permeability, formability and structural continuity. It can be cut, bent or bonded into laboratory assemblies while preserving the open pathways needed for filtration, catalytic contact, electrode loading and heat transfer. The nickel matrix also makes the foam relevant where electrical conduction, thermal response, corrosion resistance, acoustic attenuation or electromagnetic shielding must be combined with a low-mass cellular structure.

This specification is suitable for evaluating battery and fuel-cell electrodes, nickel-carbon composite electrode structures, catalyst carriers, exhaust and air-purification media, oil-water separation, industrial filtration, hydrogen electrolysis, electrocatalysis, heat-pipe wicks, condenser structures and distillation packing. Select the PPI, sheet dimensions and thickness around the intended flow, surface-area and integration requirements; choose a 1-piece pack for initial evaluation or a 5-piece pack for repeated trials and small-batch assembly.

Application Scope

Suitable for laboratory and engineering evaluations that require a 20 PPI open nickel network in a 200 × 200 × 10 mm format. Application areas include nickel-metal-hydride, nickel-cadmium and fuel-cell positive and negative electrodes; nickel-carbon composite electrodes for lithium batteries; catalyst and exhaust-purification carriers; air purification, oil-water separation and industrial filtration; hydrogen electrolysis, electrocatalysis and electrochemical metallurgy; infrared-burner surfaces and industrial or domestic drying-heater structures; heat-pipe wicks and condenser heat-transfer media; distillation-tower packing; and functional damping, acoustic, vibration-buffering, electromagnetic-shielding, thermal-insulation and decorative structures.

SELECTION GUIDANCE: Confirm PPI, nominal pore pitch, porosity requirement, through-pore rate, sheet length and width, thickness, bulk-density range, operating environment and required quantity before quotation. Confirm application-critical corrosion, temperature, mechanical and integration requirements before ordering.

HANDLING & INSPECTION: Store the sheets in a clean, dry area and protect the open cellular surface from heavy impact, crushing and contamination. After delivery, check the package condition, sheet dimensions and visible pore structure before cutting, bonding or installing the material.

IMPORTANT NOTICE: Custom dimensions are available upon consultation. For a dimensional feasibility review by e-mail, provide the target length, width, thickness, PPI and estimated quantity.

How does the 20 PPI pore density of this nickel foam influence its performance in battery electrode versus filtration applications?

The 20 PPI (approximately 1.27 mm pore pitch) provides a balance between surface area and permeability. For battery electrodes, the open-cell structure with ≥98% through-pore rate allows electrolyte flow and active material loading, while the 60–98% porosity and 0.1–0.8 g/cm³ bulk density support lightweight conductive substrates. For filtration, the 1.27 mm nominal pore size is suitable for coarse particle separation and gas/liquid flow, but finer filtration may require higher PPI grades. The product's specifications are optimized for applications like nickel-metal-hydride electrodes, catalyst carriers, and hydrogen electrolysis where both surface area and flow are critical.

Can this 200×200×10 mm nickel foam sheet be cut or bonded to fit custom electrode geometries without compromising its structural integrity?

Yes, the product description states it can be cut, bent, and bonded for downstream fabrication. The mechanical strength range of 2–7 MPa (tensile 8–50 MPa, compressive ≥250 kPa) indicates sufficient robustness for shaping while maintaining the open-pore network. However, care should be taken to avoid crushing the pores during cutting or bonding; the handling guidance recommends protecting the cellular surface from heavy impact and crushing. For custom dimensions, Atomfair offers dimensional feasibility review by email.

What storage conditions are required to maintain the performance of this 20 PPI nickel foam sheet before use?

The product should be stored in a clean, dry area and protected from heavy impact, crushing, and contamination to preserve the open-cell structure. The nickel foam is fire-resistant and recyclable, with listed temperature resistance ≥500°C, so no special climate control is needed beyond avoiding moisture that could cause surface oxidation. After delivery, inspect package condition, sheet dimensions, and visible pore structure before cutting or installing.

Assessment

This 20 PPI open-cell nickel foam sheet (200 × 200 × 10 mm) provides a high-porosity (60–98%), ≥98% through-pore network with a nominal pore pitch of 1.27 mm, suitable for electrochemical electrode substrates, catalyst carriers, and filtration media requiring combined electrical conductivity, thermal transfer, and corrosion resistance up to 500°C.

Positive

High through-pore rate and porosity: ≥98% through-pore rate with 60–98% porosity ensures unobstructed fluid flow and extensive internal surface area for electrochemical reactions or catalytic contact.
Thermal and corrosion resistance: Listed temperature resistance ≥500°C with acid/alkali tolerance allows deployment in high-temperature electrolysis, catalytic combustion, and aggressive chemical environments.

Trade-offs

Mechanical fragility under load: Compressive strength ≥250 kPa and tensile strength 8–50 MPa indicate the foam is susceptible to permanent deformation or crushing under concentrated mechanical loads, requiring careful handling and mounting.
Storage and contamination sensitivity: The open cellular surface must be stored in a clean, dry area and protected from heavy impact and contamination, as debris or moisture ingress can block pores and degrade performance in filtration or electrode applications.
