Open-Cell Nickel Foam 20 PPI 200×200×3 mm ATOMFAIR®

Laboratory Open-Cell Nickel Foam, 20 PPI, 200 × 200 × 3 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 × 3 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.

Suitable for laboratory and engineering evaluations that require a 20 PPI open nickel network in a 200 × 200 × 3 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.

What is the typical porosity range and through-pore rate of the 20 PPI nickel foam, and how do these properties affect its suitability for electrochemical electrode applications?

The foam has a porosity range of 60–98% and a through-pore rate of at least 98%, ensuring extensive internal surface area and unimpeded flow of electrolytes and reactants. This combination makes it suitable for battery and fuel-cell electrodes where high active surface area and low flow resistance are critical.

Can this 200×200×3 mm nickel foam sheet be integrated into a hydrogen electrolysis cell without additional surface treatment?

Yes, the open-cell nickel structure provides electrical conductivity and corrosion resistance under alkaline conditions, as indicated by its listed resistance to acid/alkali environments and high-temperature stability above 500°C. However, for specific catalyst loading or long-term durability, additional coatings or pre-treatments may be required depending on the electrolysis chemistry.

What are the recommended storage and handling procedures to maintain the structural integrity of the nickel foam before use?

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 material.

Assessment

This 20 PPI open-cell nickel foam sheet (200×200×3 mm) provides a highly porous, electrically conductive nickel network with ≥98% through-pore rate and temperature resistance up to >1100°C, making it suitable for electrochemical and catalytic applications. However, its modest mechanical strength (tensile 8–50 MPa, compressive ≥250 kPa) demands careful handling to avoid structural damage.

Positive

High through-pore rate and porosity: The ≥98% through-pore rate and 60–98% porosity ensure excellent permeability for gases, liquids, and electrochemical reactants, critical for battery electrodes and catalyst carriers.
High temperature and thermal performance: With a stated temperature resistance ≥500°C and capability >1100°C, along with a heat-transfer coefficient >3 W/(m²·K), this foam supports high-temperature and heat-transfer applications.

Trade-offs

Modest mechanical strength: Tensile strength of 8–50 MPa and compressive strength ≥250 kPa indicate the foam is relatively fragile and must be protected from crushing, heavy impact, and deformation during handling and integration.
Handling and storage sensitivity: The open-cell structure and thin 3 mm sheet require storage in a clean, dry area and protection from contamination and physical damage, as specified in the handling instructions.
