Closed-Cell Aluminum Foam, 3–4 mm Pore Size, 100 × 200 × 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 × 200 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 × 200 mm format does not match the planned installation, prototype or experimental setup.

  • 100 × 200 mm finished sheet size and 5 mm nominal thickness.
  • 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.

This closed-cell aluminum foam sheet requires storage in a clean, dry environment to prevent contamination and structural damage. The cellular surface must be protected from heavy impact, crushing, and contamination during handling and storage.

  • Storage Environment: Store the sheets in a clean, dry area to maintain material integrity and prevent contamination.
  • Impact Protection: Protect the cellular surface from heavy impact and crushing during storage and handling.
  • Contamination Prevention: Avoid exposing the material to contaminants that could compromise the cellular structure.
  • Pre-Use Inspection: Inspect the package condition, sheet dimensions, and visible pore structure before cutting, bonding, or installing the material.

Can this closed-cell aluminum foam sheet be used for electromagnetic interference (EMI) shielding?

Yes, the product is listed for electromagnetic-shielding evaluations. The closed-cell aluminum-alloy framework provides a conductive metallic cellular medium that can attenuate electromagnetic fields. However, specific shielding effectiveness values are not provided; users should test for their frequency range and application.

What is the typical porosity range of this aluminum foam and how does it affect density and mechanical properties?

The typical porosity is 70–90%. Higher porosity reduces density but also reduces mechanical strength. The closed-cell structure provides independent sealed pores, so the foam maintains structural integrity while being lightweight. Exact density and mechanical properties are not specified; users should evaluate based on their requirements.

How should this closed-cell aluminum foam sheet be stored and handled to maintain its performance?

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. Avoid applying excessive force that could collapse the closed cells, as this would compromise energy absorption and structural properties.

This closed-cell aluminum foam sheet (3–4 mm pore size, 5 mm thick, 100 × 200 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 a non-translucent metallic barrier is required.
  • 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 damage: The cellular surface must be protected from heavy impact and crushing during handling and storage, as the porous structure can deform permanently under concentrated loads.
  • Requires clean, dry storage: Sheets must be stored in a clean, dry area to prevent contamination or moisture ingress into the sealed pores, which could affect structural integrity or application performance.
