Open-Cell Aluminum Foam, 2–3 mm Pore Size, 200 × 200 × 3–4 mm, 5/10 pcs
Research-grade laboratory product
Product Overview

Open-cell aluminum foam is a lightweight porous-metal sheet formed from an aluminum-alloy cellular framework. Its interconnected pore network combines a high internal surface area with continuous open passages, making it suitable for laboratory evaluation, prototype construction and engineering projects that require a controlled porous structure.

This configuration has a 2–3 mm pore-size range, a finished sheet size of 200 × 200 mm and a nominal thickness of 3–4 mm. Typical porosity is 70–90%. The typical open-cell rate is 55–65%. These parameters help users compare passage geometry, surface-contact behavior and integration requirements.

The open structure can support heat-transfer and heat-dissipation studies, gas or liquid filtration assemblies, acoustic-control experiments, light-transmitting structures and other applications where a rigid metallic porous medium is required. The aluminum framework also makes the sheet convenient for integration into test fixtures, layered assemblies, prototype housings and cut-to-fit research components.

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 200 × 200 mm format does not match the planned installation, prototype or experimental setup.

Application Scope

Suitable for porous-metal research, heat-transfer and heat-dissipation studies, gas or liquid filtration assemblies, acoustic-control experiments, light-transmitting structures and laboratory fixtures that require a rigid, interconnected open-cell medium. The sheet can also be evaluated as a flow-distribution layer, porous support, structural insert or cut-to-fit component 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 aluminum foam sheets in a clean, dry environment to prevent moisture-induced oxidation. Protect the cellular structure from heavy impact, crushing, and particulate contamination that could compromise open-cell integrity.

  • Storage Environment: Maintain storage in a dry area with relative humidity below 60% to avoid surface oxidation.
  • Impact Protection: Avoid heavy loads or compressive forces on the sheets to prevent permanent deformation of the pore network.
  • Contamination Prevention: Keep the open-cell surface free from dust, oils, and debris to maintain unimpeded fluid passage.
  • Pre-Use Inspection: Verify sheet dimensions and pore structure against specifications before cutting, bonding, or installation.

Inspect the sheets immediately upon delivery to confirm dimensional accuracy and structural integrity. Store the material in a controlled environment to preserve its open-cell properties until use.

Required Equipment: Clean, dry storage area, Measuring instruments (caliper, ruler)

  1. Inspect Delivery Package
    Examine the package for signs of crushing or damage that could affect the foam sheets.
  2. Verify Dimensions and Pore Structure
    Measure the sheet length, width, and thickness, and visually confirm the pore size and open-cell distribution.
  3. Store in Controlled Environment
    Place the sheets flat in a clean, dry storage area, away from heavy objects and potential contaminants.

How does the 55–65% open-cell rate compare to the 70–90% porosity, and what does that mean for fluid permeability?

The open-cell rate (55–65%) measures the proportion of fully interconnected pores, while porosity (70–90%) measures total void volume. This indicates that although the foam has high void volume, only about half to two-thirds of the pores are continuous through-paths. For fluid permeability, the open-cell rate is the more direct determinant; higher values within the range favor lower pressure drop, while the porosity provides the overall surface area. The specific pore size (2–3 mm) and thickness (3–4 mm) also influence flow behavior, so experimental validation under target conditions is recommended.

What mounting methods are compatible with the 200×200×3–4 mm open-cell aluminum foam sheet?

The source states the sheet can be integrated into test fixtures, layered assemblies, prototype housings, and cut-to-fit components. It can be cut, bonded, or installed, but the manufacturer recommends inspecting dimensions and pore structure before cutting, bonding, or installing. The rigid aluminum-alloy framework supports mechanical fastening or adhesive bonding, though the open-cell structure must be protected from crushing during mounting. No specific adhesive or fastener type is prescribed, so compatibility with the intended medium and operating environment should be verified.

What are the key storage and handling requirements to maintain the structural integrity of open-cell aluminum foam?

Store the sheets in a clean, dry area and protect the cellular surface from heavy impact, crushing, and contamination, as stated in the handling guidance. After delivery, inspect the package condition, sheet dimensions, and visible pore structure before cutting, bonding, or installing. These precautions prevent pore blockage and mechanical damage that could compromise the foam's performance in heat transfer, filtration, or acoustic applications.

This open-cell aluminum foam sheet with 2–3 mm pore size and 70–90% porosity provides a lightweight, rigid porous medium for heat transfer, filtration, and acoustic studies, but requires careful handling and may need dimensional customization for non-standard integrations.

Positive

  • Interconnected open-pore network: The 2–3 mm pore size with 70–90% porosity and 55–65% open-cell rate provides continuous passages for airflow, fluid passage, and light transmission, enabling heat transfer, filtration, and acoustic control experiments.
  • Lightweight rigid aluminum framework: The aluminum-alloy cellular structure offers a lightweight yet rigid porous medium suitable for easy integration into test fixtures, layered assemblies, and prototype housings.

Trade-offs

  • Requires careful handling and storage: The cellular surface must be protected from heavy impact, crushing, and contamination; storage in a clean, dry area is necessary to maintain structural integrity.
  • Fixed sheet dimensions may limit direct fit: Standard sheet size of 200 × 200 × 3–4 mm may require dimensional customization for specific experimental setups, which must be discussed with the supplier.
