Closed-Cell Aluminum Foam, 3–4 mm Pore Size, 100 × 100 × 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 100 × 100 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 100 × 100 mm format does not match the planned installation, prototype or experimental setup.

  • Independent sealed pores create a non-translucent metallic cellular structure.
  • The closed-cell geometry is suited to energy absorption, impact buffering and lightweight panel use.
  • A lightweight aluminum-alloy framework supports integration into structural and shielding prototypes.
  • 70–90% (typical) porosity; an open-cell-rate value is not applicable to the sealed-cell configuration.
  • Available in 5-piece and 10-piece package quantities.
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.

Store closed-cell aluminum foam sheets in a clean, dry environment to prevent contamination and moisture ingress. Protect the cellular surface from heavy impact, crushing, and mechanical deformation to maintain structural integrity.

  • Storage Environment: Store sheets in a clean, dry area to avoid contamination and moisture-related degradation.
  • Mechanical Protection: Protect the cellular surface from heavy impact, crushing, and contamination to prevent structural damage.
  • Pre-Use Inspection: Verify package condition, sheet dimensions, and visible pore structure before cutting, bonding, or installing the material.
  • Mounting Compatibility: Consider the intended mounting method, surrounding medium, and operating conditions when integrating the foam into an assembly.

Inspect the foam upon receipt and store it in a clean, dry environment. Protect the cellular structure from impact and contaminants before integrating into an assembly.

Required Equipment:

  1. Inspect Delivery
    Inspect the package condition, sheet dimensions, and visible pore structure upon delivery before any processing.
  2. Store Properly
    Store the sheets in a clean, dry area to prevent contamination and moisture ingress.
  3. Protect Surface
    Protect the cellular surface from heavy impact, crushing, and contamination during handling and storage.
  4. Assess Integration
    Consider the intended mounting method, medium, and operating conditions when integrating the foam into an assembly.

How does the 70–90% porosity range of the Atomfair AF-C34-10-T08 closed-cell aluminum foam affect its energy absorption performance?

The typical porosity of 70–90% directly influences the foam's density and crush behavior. Higher porosity reduces mass but also lowers the plateau stress available for energy absorption, while lower porosity increases structural stiffness and impact resistance. The independent closed-pore structure ensures that deformation is localized within individual cells, making the material suitable for impact-buffering studies and lightweight structural filling where predictable crush response is required.

Can the Atomfair closed-cell aluminum foam sheet be integrated into electromagnetic shielding prototypes?

Yes, the product is listed as suitable for electromagnetic-shielding evaluations. Its non-translucent closed-cell metallic framework provides a continuous conductive path that can attenuate electromagnetic fields, though exact shielding effectiveness depends on frequency, sheet thickness (8 mm), and integration method. The 100 × 100 mm format allows direct use in test fixtures or cut-to-fit shielding panels.

What storage and handling precautions are recommended for the Atomfair 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 the package condition, sheet dimensions, and visible pore structure before cutting, bonding, or installing the material. These precautions preserve the closed-cell geometry and prevent damage that could compromise energy absorption or structural integrity.

This closed-cell aluminum foam sheet (3–4 mm pore size, 100 × 100 × 8 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 applications requiring a non-translucent, isolated-cell medium such as sound insulation panels or electromagnetic shielding prototypes.
  • Lightweight aluminum-alloy framework: The foamed aluminum alloy provides low structural mass with typical porosity of 70–90%, enabling integration into lightweight sandwich structures and impact-buffering components without significant weight penalty.

Trade-offs

  • Susceptible 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 deformation before use.
  • Fixed sheet dimensions limit flexibility: The standard 100 × 100 × 8 mm format may not match all experimental setups; dimensional customization requires consultation and feasibility review, adding lead time for non-standard applications.
