Closed-Cell Aluminum Foam 3–4 mm, 200×200×8 mm ATOMFAIR®

Closed-Cell Aluminum Foam, 3–4 mm Pore Size, 200 × 200 × 8 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 200 × 200 mm and a nominal thickness of 8 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 200 × 200 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.

How does the 3–4 mm pore size and 8 mm thickness of the Atomfair AF-C34-20-T08 closed-cell aluminum foam affect its energy absorption characteristics?

The closed-cell geometry with 3–4 mm pores and 8 mm thickness is explicitly suited for energy absorption and impact buffering studies per the product description. The independent sealed cells provide a lightweight metallic cellular body that can be integrated into impact-buffering components and protective housings. Specific energy absorption values are not stated; the material is intended for laboratory evaluation and prototype construction where these parameters can be empirically tested.

Can the closed-cell aluminum foam sheet be cut or machined to custom dimensions without damaging the sealed cell structure?

The product description indicates that dimensional customization can be discussed when the standard 200×200 mm format does not match the planned setup, and it advises checking the visible pore structure before cutting, bonding, or installing. This implies cutting is possible, but care must be taken to avoid crushing or contamination. No specific machining guidelines are provided; contact engineering sales for application-specific guidance.

What is the difference between closed-cell and open-cell aluminum foam in terms of sound insulation performance?

This product features independent sealed pores suitable for sound-insulation panels, whereas open-cell foams have interconnected pores that allow air and sound transmission. The closed-cell structure provides a non-translucent metallic cellular medium that can block sound more effectively. The source does not provide quantitative sound transmission loss data; it is intended for research evaluation.

Assessment

This closed-cell aluminum foam sheet (200×200×8 mm, 3–4 mm pore size) provides a lightweight, non-translucent metallic cellular structure with independent sealed pores, suitable 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 eliminates open-cell pathways, making the sheet suitable for applications requiring non-translucent metallic media, such as electromagnetic shielding and sound insulation, where through-thickness fluid or light transmission must be avoided.
Lightweight aluminum-alloy framework: With typical porosity of 70–90%, the foamed aluminum alloy provides low structural mass while retaining a metallic cellular body, enabling integration into lightweight sandwich panels, protective housings, and test fixtures without significant weight penalty.

Trade-offs

Susceptibility to crushing damage: The cellular surface is vulnerable to heavy impact and crushing during handling or installation, requiring careful storage in a clean, dry area and protection from mechanical loads to preserve pore integrity and structural performance.
Fixed sheet dimensions limit flexibility: The standard 200×200×8 mm format may not match all experimental setups or prototype geometries; dimensional customization requires consultation and feasibility review, adding lead time for non-standard applications.
