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

Key Features and Advantages
  • 3–4 mm pore-size range with a independent closed-pore structure.
  • 100 × 200 mm finished sheet size and 8 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.

Store the closed-cell aluminum foam sheets in a clean, dry environment to prevent contamination and surface degradation. Protect the cellular structure from heavy impact, crushing forces, and abrasive contact to maintain structural integrity.

  • Storage Environment: Maintain a clean, dry storage area to avoid moisture uptake and particulate contamination on the porous metallic surface.
  • Mechanical Protection: Protect the sheets from heavy impact, crushing, and abrasive contact to preserve the integrity of the closed-cell structure.
  • Pre-Processing Inspection: Verify sheet dimensions, pore structure, and freedom from visible damage prior to cutting, bonding, or installation.

What storage and handling precautions are required for Atomfair closed-cell aluminum foam sheets to maintain structural integrity?

Store 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, bonding, or installing. These precautions are specified in the product's handling and inspection guidelines.

Can the standard 100 × 200 × 8 mm sheet dimensions be customized for specific research setups?

Yes, custom dimensions are available upon consultation. To initiate a dimensional feasibility review, provide the target length, width, thickness, pore-size range, and estimated quantity to the engineering sales team as stated in the product's important notice.

How does the closed-cell structure of this aluminum foam differ from open-cell foam for electromagnetic shielding evaluations?

The closed-cell structure features independent sealed pores, creating a non-translucent metallic cellular body that can support electromagnetic-shielding evaluations as listed in typical applications. Unlike open-cell foams, an open-cell rate is not applicable because the pores are sealed, which may affect shielding continuity. Specific shielding effectiveness values are not provided in the product description.

This closed-cell aluminum foam sheet (3–4 mm pore size, 100 × 200 × 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. The 70–90% porosity and fixed sheet dimensions require careful confirmation of application fit before ordering.

Positive

  • Independent closed-pore structure: The sealed-cell geometry provides a non-translucent metallic cellular medium with predictable mechanical and acoustic behavior, ideal for energy absorption and sound insulation studies without fluid or gas permeability.
  • Lightweight aluminum-alloy framework: The foamed aluminum alloy offers low structural mass (70–90% porosity) while maintaining a metallic cellular body, enabling integration into lightweight structural panels, sandwich cores, and shielding prototypes.

Trade-offs

  • Fixed sheet dimensions require confirmation: The standard 100 × 200 × 8 mm format may not match all experimental setups; dimensional customization requires consultation and feasibility review before ordering.
  • Sensitive to heavy impact and contamination: The cellular surface must be stored in a clean, dry area and protected from crushing and contamination to maintain structural integrity during handling, cutting, bonding, or installation.
