Closed-Cell Aluminum Foam 3–4 mm Pores, 5 mm ATOMFAIR®

Closed-Cell Aluminum Foam, 3–4 mm Pore Size, 100 × 100 × 5 mm, 5/10 pcs

Research-grade laboratory product

Product Overview

Closed-cell aluminum foam is a lightweight porous-metal sheet formed from an aluminum-alloy framework containing independent, sealed cells. The closed-pore geometry combines low structural mass with a metallic cellular body, making it suitable for laboratory evaluation, prototype construction and engineering projects that require impact management, sound control or lightweight structural filling.

This configuration has a 3–4 mm pore-size range, a finished sheet size of 100 × 100 mm and a nominal thickness of 5 mm. Typical porosity is 70–90%. Because the pores are independent and sealed, an open-cell-rate value does not apply. These parameters help users compare cellular geometry, structural behavior and integration requirements.

The isolated-cell structure can support energy-absorption studies, impact-buffering components, sound-insulation panels, lightweight sandwich structures and electromagnetic-shielding evaluations. The sheet can also be integrated into test fixtures, protective housings, layered assemblies and cut-to-fit research components where a non-translucent metallic cellular medium is preferred.

Before ordering, confirm the required pore-size range, sheet length and width, thickness, package quantity and intended operating environment. Dimensional customization can be discussed when the standard 100 × 100 mm format does not match the planned installation, prototype or experimental setup.

Application Scope

Suitable for porous-metal research, energy-absorption and impact-buffering studies, sound-insulation assemblies, lightweight structural panels, electromagnetic-shielding evaluations and laboratory fixtures that require an independent closed-cell medium. The sheet can also be evaluated as a protective insert, sandwich-panel core, enclosure component or cut-to-fit part in research and engineering assemblies.

SELECTION GUIDANCE: Confirm the pore-size range, porosity requirement, cell structure, sheet length and width, thickness and required quantity before quotation. The intended medium, mounting method and surrounding operating conditions should also be considered when matching the material to an experimental or engineering setup.

HANDLING & INSPECTION: Store the sheets in a clean, dry area and protect the 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, provide the target length, width, thickness, pore-size range and estimated quantity.

What is the typical porosity range of this closed-cell aluminum foam and how does it affect its weight and structural properties?

The typical porosity is 70–90%. This high porosity results in a lightweight metallic cellular structure suitable for energy absorption and impact buffering. The closed-cell geometry provides independent sealed pores, contributing to structural integrity while maintaining low mass.

Can this closed-cell aluminum foam sheet be cut or bonded to custom dimensions for integration into experimental setups?

Yes, the sheet can be cut to fit research components. The product description states that dimensional customization is available upon consultation, and the material can be cut, bonded, or installed. Users should confirm target dimensions with the engineering sales team for feasibility.

What storage and handling precautions are required to maintain the integrity of the closed-cell aluminum foam sheets?

Store the sheets in a clean, dry area and protect the cellular surface from heavy impact, crushing, and contamination. After delivery, inspect package condition, sheet dimensions, and visible pore structure before cutting or installing. These precautions help preserve the closed-cell structure and performance.

Assessment

This closed-cell aluminum foam sheet (3–4 mm pore size, 100 × 100 × 5 mm) provides a lightweight, non-translucent metallic cellular structure with independent sealed pores, suited for energy absorption, impact buffering, sound insulation, and electromagnetic shielding evaluations in laboratory and prototype settings.

Positive

Independent closed-pore structure: The sealed-cell geometry prevents fluid or gas permeation, making the sheet suitable for sound insulation and electromagnetic shielding applications where open-cell foams would not be effective.
Lightweight aluminum-alloy framework: The foamed aluminum alloy provides low structural mass (70–90% porosity) while maintaining a metallic cellular body, enabling integration into lightweight sandwich panels and impact-buffering components without significant weight penalty.

Trade-offs

Susceptible to crushing and contamination: The cellular surface must be stored in a clean, dry area and protected from heavy impact or crushing, as the porous structure can be permanently deformed or contaminated, compromising its performance in energy absorption or shielding studies.
Fixed sheet dimensions limit integration flexibility: The standard 100 × 100 × 5 mm format may not match all experimental setups or prototype geometries; custom dimensions require consultation and feasibility review, adding lead time for non-standard applications.
