Open-Cell Nickel Foam 20 PPI 100×200×20 mm ATOMFAIR®

Laboratory Open-Cell Nickel Foam, 20 PPI, 100 × 200 × 20 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 100 × 200 × 20 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 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.

FAQ

How does the 20 PPI pore density and 1.27 mm nominal pore pitch influence the trade-off between surface area and flow permeability for electrochemical electrode applications?

The 20 PPI structure provides a nominal pore pitch of 1.27 mm, balancing extensive internal surface exposure with a high through-pore rate of at least 98% and a porosity range of 60–98%. This allows gases and liquids to move through the material while maintaining sufficient surface area for catalytic contact and electrode loading, making it suitable for battery and fuel-cell electrodes where both reactant transport and active material deposition are critical.

Can this open-cell nickel foam be integrated directly into a hydrogen electrolysis cell as a porous transport layer without additional surface treatment?

The nickel foam is suitable for hydrogen electrolysis and electrocatalysis applications due to its continuous three-dimensional nickel skeleton, electrical conductivity, and corrosion resistance under acid/alkali conditions. However, the source does not specify whether additional surface treatments or coatings are required for specific electrolysis configurations; users should confirm compatibility with their operating environment and integration requirements before ordering.

What storage and handling precautions are necessary to preserve the structural integrity and pore uniformity of the 20 mm thick nickel foam sheet?

Store the sheets in a clean, dry area and protect the open cellular surface from heavy impact, crushing, and contamination. After delivery, inspect package condition, sheet dimensions, and visible pore structure before cutting, bonding, or installing. The foam can be cut, bent, or bonded, but care must be taken to avoid deforming the 20 mm thick open-cell network.

Assessment

This 20 PPI open-cell nickel foam sheet (100 × 200 × 20 mm) offers a high-surface-area, highly permeable porous network with ≥98% through-pore rate and 60–98% porosity, making it suitable for electrode, catalysis, filtration, and heat-transfer applications. Its thermal stability up to 1100°C and lightweight metallic structure enable integration into high-temperature or weight-sensitive systems, but the open cellular structure requires careful handling and environment-specific corrosion verification.

Positive

High porosity and through-pore rate: With 60–98% porosity and ≥98% through-pore rate, the 20 PPI open network provides extensive internal surface area and efficient fluid permeation, supporting catalytic contact, electrode loading, and filtration flow.
Thermal resistance up to 1100°C: Listed high-temperature capability above 1100°C and heat-transfer coefficient >3 W/(m²·K) enable use in high-temperature processes such as hydrogen electrolysis, combustion surfaces, and heat-pipe wicks without structural degradation.

Trade-offs

Sensitive to mechanical damage: The open cellular structure must be protected from heavy impact, crushing, and contamination during storage and handling; physical damage can compromise pore integrity and flow performance.
Corrosion and environment verification required: While the foam resists high temperatures and acid/alkali conditions generally, the product literature explicitly requires confirming application-critical corrosion, temperature, and mechanical requirements before ordering, indicating that compatibility is not universal.
