Laboratory Open-Cell Nickel Foam, 40 PPI, 200 × 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 200 × 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 Scope

Suitable for laboratory and engineering evaluations that require a 40 PPI open nickel network in a 200 × 200 × 20 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 40 PPI pore density of this nickel foam influence its performance in gas diffusion electrodes compared to liquid filtration applications?

The 40 PPI structure with a nominal pore pitch of 0.64 mm and ≥98% through-pore rate supports efficient gas diffusion in fuel cell electrodes while also enabling liquid flow for filtration. The high porosity (60–98%) ensures extensive surface area for catalytic reactions, but the exact trade-off between permeability and surface area depends on the specific application requirements.

What are the temperature and chemical compatibility limits of this nickel foam when used in acidic or alkaline electrolysis environments?

The nickel foam is listed with temperature resistance ≥500°C and high-temperature capability >1100°C, and it is described as resistant to acid/alkali conditions. However, the source does not specify exact pH ranges or concentration limits. For alkaline electrolysis (e.g., KOH), nickel is generally stable, but for acidic environments, corrosion resistance should be verified under operating conditions.

What mechanical precautions are necessary when cutting or bonding this 20 mm thick nickel foam to avoid structural damage?

The foam has a compressive strength ≥250 kPa and tensile strength of 8–50 MPa, indicating it can withstand moderate handling but is susceptible to crushing under heavy impact. The manufacturer advises protecting the open cellular surface from heavy impact, crushing, and contamination. Cutting can be done with sharp tools to minimize pore deformation, and bonding should use methods that do not clog the open network.

This 40 PPI open-cell nickel foam sheet in a 200 × 200 × 20 mm format offers a high-porosity (60–98%) three-dimensional network with ≥98% through-pore rate, balancing low density (0.1–0.8 g/cm³) with mechanical integrity (≥2–7 MPa) and high-temperature resistance beyond 1100°C, making it suitable for electrochemical, filtration, and heat-transfer applications though it requires careful handling and application-specific validation.

Positive

  • High porosity and through-pore rate: The 60–98% porosity with ≥98% through-pore rate ensures open, continuous pathways for gases and liquids, critical for electrode loading, filtration, and catalytic contact.
  • High-temperature and thermal performance: Listed temperature resistance above 1100°C and heat-transfer coefficient >3 W/(m²·K) support use in high-temperature catalytic, electrolysis, and heat-transfer assemblies.

Trade-offs

  • Requires careful handling and storage: The open cellular structure must be protected from heavy impact, crushing, and contamination, and stored in a clean dry area to maintain its mechanical and flow properties.
  • Application-specific validation needed: Selection guidance mandates confirming corrosion, temperature, mechanical, and integration requirements before ordering, indicating the foam's performance depends on the exact operating environment.
