Closed-Cell Aluminum Foam, 2–3 mm Pore Size, 100 × 200 × 20 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 2–3 mm pore-size range, a finished sheet size of 100 × 200 mm and a nominal thickness of 20 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.

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.

These closed-cell aluminum foam sheets require specific storage and handling to maintain structural integrity. The sealed-pore cellular structure is susceptible to crushing and contamination if mishandled.

  • Storage Environment: Store sheets in a clean, dry area to prevent moisture absorption and contamination of the cellular matrix.
  • Impact Protection: Protect the cellular surface from heavy impact and crushing forces that could collapse the closed-pore structure.
  • Pre-Use Inspection: Verify package condition, sheet dimensions, and visible pore structure before cutting, bonding, or installing the material.

Proper handling and inspection ensure the aluminum foam sheets perform as intended. Follow these steps to store, inspect, and prepare the material for integration.

  1. Inspect Delivery
    Inspect the delivered sheets for package condition and dimensional accuracy against the ordered specifications.
  2. Store Sheets
    Store sheets in a clean, dry environment away from heavy traffic and potential contamination sources.
  3. Protect Surface
    Protect the cellular surface from impact, crushing, and contamination during handling and storage.
  4. Verify Structure
    Verify the pore structure and sheet dimensions before cutting, bonding, or installing the material.
  5. Cut or Bond
    Cut or bond the sheet as required for your application, using appropriate methods to avoid damaging the cellular structure.

What are the key performance characteristics of this closed-cell aluminum foam for energy absorption applications?

The closed-cell aluminum foam absorbs energy through plastic deformation of its aluminum-alloy framework under impact. With a typical porosity of 70–90% and a pore size of 2–3 mm, the independent sealed pores ensure consistent crush behavior without gas escape, making it suitable for impact-buffering components and protective inserts as described in the application scope.

Can this closed-cell aluminum foam sheet be bonded or integrated into sandwich panel structures?

Yes, the 100 × 200 × 20 mm sheet can be integrated into lightweight sandwich structures as a core material. The aluminum-alloy framework allows bonding with structural adhesives, and the closed-cell geometry prevents adhesive penetration into pores. The product is explicitly listed for use in lightweight sandwich structures and cut-to-fit research components.

What storage and handling precautions are required for this closed-cell aluminum foam?

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 are specified in the product's handling and inspection guidance.

This closed-cell aluminum foam sheet (2–3 mm pore size, 100 × 200 × 20 mm) 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 prevents fluid or gas permeation, making the sheet suitable for applications requiring a non-translucent metallic cellular medium, such as sound insulation panels or electromagnetic shielding assemblies.
  • Lightweight aluminum-alloy framework: With typical porosity of 70–90%, the sheet offers low structural mass while maintaining a metallic cellular body, enabling integration into lightweight sandwich structures, protective housings, 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 mechanical and shielding performance.
  • Fixed sheet dimensions limit direct fit: The standard 100 × 200 × 20 mm format may not match all experimental setups or prototype enclosures; dimensional customization requires consultation and feasibility review, adding lead time for non-standard applications.
