Closed-Cell Aluminum Foam, 2–3 mm Pore Size, 100 × 100 × 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 × 100 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 × 100 mm format does not match the planned installation, prototype or experimental setup.

Key Features and Advantages
  • 2–3 mm pore-size range with a independent closed-pore structure.
  • 100 × 100 mm finished sheet size and 20 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 moisture exposure and contamination. Protect the cellular surface from heavy impact, crushing, and particulate contamination to maintain structural integrity.

  • Moisture and Dry Storage: Store the sheets in a clean, dry area to avoid moisture absorption and corrosion of the aluminum alloy framework.
  • Mechanical Protection: Protect the cellular surface from heavy impact and crushing forces that could deform the closed-pore structure.
  • Contamination Control: Prevent particulate contamination on the surface to maintain the material's structural and functional properties.

How does the 70–90% porosity range of this closed-cell aluminum foam affect its suitability for energy absorption versus sound insulation?

The 70–90% porosity range provides a lightweight cellular structure that balances energy absorption and sound insulation. The independent sealed pores are effective for impact buffering and sound attenuation, as stated in the product's typical applications. The closed-cell geometry prevents fluid or gas permeation, making it suitable for structural damping and acoustic isolation in laboratory and engineering assemblies.

Can this closed-cell aluminum foam sheet be cut, bonded, or integrated into sandwich panels without compromising its closed-cell structure?

Yes, the sheet can be cut, bonded, or integrated into sandwich structures and test fixtures. The product description notes it can be used as a sandwich-panel core, protective insert, or cut-to-fit part. However, care must be taken to avoid crushing the cellular surface during handling and installation, as recommended in the handling and inspection guidelines.

What storage conditions are required to maintain the integrity of the 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 package condition, sheet dimensions, and visible pore structure before cutting, bonding, or installing. These guidelines are provided in the product's handling and inspection section.

This closed-cell aluminum foam sheet (100 × 100 × 20 mm, 2–3 mm pore size) provides a lightweight, non-translucent metallic cellular structure with 70–90% porosity, suitable for energy absorption, impact buffering, sound insulation, and electromagnetic shielding evaluations in laboratory and prototype settings.

Positive

  • Closed-pore geometry for energy absorption: The independent sealed cells create a non-translucent metallic structure that supports impact buffering, sound insulation, and lightweight panel integration without fluid or gas permeability.
  • Standardized sheet size and porosity range: The 100 × 100 × 20 mm format with 70–90% typical porosity allows direct comparison across experiments and simplifies integration into test fixtures, sandwich panels, or shielding prototypes.

Trade-offs

  • Requires clean, dry storage conditions: The cellular surface must be stored in a clean, dry area and protected from heavy impact, crushing, and contamination to preserve structural integrity before use.
  • Limited to standard dimensions without consultation: The product is supplied as a fixed 100 × 100 × 20 mm sheet; custom dimensions require a dimensional feasibility review with the manufacturer, adding lead time for non-standard setups.
