Laboratory Nickel Foam Sheet 40 PPI 100×200×20 mm ATOMFAIR®

Laboratory Open-Cell Nickel Foam, 40 PPI, 100 × 200 × 20 mm, 1/5 pcs

Research-grade laboratory product

Product Overview

Open-cell nickel foam with 40 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 0.64 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.

How does the 40 PPI and 0.64 mm nominal pore pitch affect the balance between fluid permeability and available surface area for electrochemical reactions?

The 40 PPI with approximately 0.64 mm nominal pore pitch provides a regular open network that balances high through-pore rate (≥98%) and porosity (60–98%) with extensive internal surface exposure. This allows gases, liquids, and electrochemical reactants to move through the material while maintaining sufficient surface contact for electrode loading or catalytic reactions. The bulk density range of 0.1–0.8 g/cm³ and tensile strength of 8–50 MPa indicate the structure remains lightweight yet mechanically robust under flow conditions.

Is this nickel foam chemically compatible with alkaline electrolytes used in hydrogen electrolysis and fuel cells?

Yes, the nickel matrix is listed as resistant to acid/alkali conditions, making it suitable for alkaline electrolysis and fuel-cell environments. The open-cell structure with ≥98% through-pore rate ensures electrolyte penetration, and the temperature resistance of ≥500°C (up to >1100°C) supports elevated operating temperatures common in these processes. However, confirm specific corrosion resistance for your electrolyte concentration and temperature before use.

What are the recommended methods for cutting and bonding this 20 mm thick nickel foam without collapsing the pore structure?

The foam can be cut, bent, and bonded using standard metalworking tools; for clean cuts, use a sharp blade or wire EDM to minimize pore deformation. Bonding can be achieved with conductive epoxies or spot welding, preserving the open pathways. The material's mechanical strength (≥2–7 MPa) and tensile strength (8–50 MPa) indicate it can withstand handling without structural collapse if proper techniques are used.

Assessment

This 40 PPI open-cell nickel foam sheet (100×200×20 mm) provides a high-porosity, thermally stable nickel skeleton for electrochemical and filtration applications, but its low mechanical strength and fixed dimensions require careful handling and potential custom ordering.

Positive

High porosity and through-pore rate: The 60–98% porosity combined with ≥98% through-pore rate ensures extensive internal surface area and unimpeded fluid flow, critical for electrode loading, catalysis, and filtration.
Thermal and chemical stability: With listed temperature resistance ≥500°C and capability >1100°C, plus resistance to acid/alkali conditions, the foam is suitable for high-temperature and corrosive electrochemical environments.

Trade-offs

Low mechanical robustness: The low bulk density (0.1–0.8 g/cm³) and moderate tensile strength (8–50 MPa) make the foam susceptible to deformation or damage under heavy impact or crushing, requiring careful handling and storage.
Fixed standard sheet dimensions: The standard 100×200×20 mm sheet may not fit all setups; custom dimensions require consultation and lead time, which may limit rapid prototyping or integration.
