Open-Cell Aluminum Foam, 3–4 mm Pore Size, 100 × 100 × 5 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 3–4 mm pore-size range, a finished sheet size of 100 × 100 mm and a nominal thickness of 5 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 100 × 100 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 sheets in a clean, dry environment to prevent contamination and oxidation. Protect the cellular structure from mechanical damage including impact, crushing, and deformation during handling and integration.

  • Clean Storage: Keep the sheets in a clean, dry area free from dust and moisture.
  • Impact Protection: Avoid heavy impact, crushing, or pressure that could deform the open-cell structure.
  • Inspection: Inspect the package condition, sheet dimensions, and pore structure upon delivery before use.

Follow these steps to ensure proper handling and inspection of the foam sheets upon receipt. Proper storage and protection maintain the material integrity for experimental use.

Required Equipment:

  1. Inspect Upon Delivery
    Check the package condition, sheet dimensions, and visible pore structure immediately after delivery.
  2. Store in Clean Area
    Store the sheets in a clean, dry environment to prevent contamination and moisture exposure.
  3. Protect From Damage
    Protect the cellular surface from heavy impact, crushing, and deformation during handling and integration.

What is the significance of the 55–65% open-cell rate for heat dissipation applications using this aluminum foam?

The 55–65% open-cell rate indicates that a majority of the pores are interconnected, creating continuous passages for convective airflow while the remaining closed cells contribute to structural rigidity. This balance supports heat dissipation studies by allowing fluid flow through the metallic framework without compromising mechanical integrity, as stated in the product's typical applications for heat transfer and dissipation.

Can the 100×100×5 mm open-cell aluminum foam sheet be cut to custom dimensions without damaging the pore structure?

Yes, but careful cutting methods such as wire EDM or abrasive cutting are recommended to avoid crushing the cellular network. The product description notes that custom dimensions are available upon consultation with the engineering sales team, and handling instructions advise protecting the sheet from heavy impact and crushing during modification.

What storage conditions are recommended to prevent contamination or deformation of the aluminum foam sheets?

Store the sheets in a clean, dry area and protect them from heavy impact, crushing, and contamination as specified in the handling and inspection guidelines. Keeping the sheets in their original packaging until use helps maintain the open-pore structure free from debris or mechanical damage.

This open-cell aluminum foam sheet (3–4 mm pore size, 100 × 100 × 5 mm) provides a rigid, interconnected porous medium with typical porosity of 70–90% and open-cell rate of 55–65%, suitable for heat-transfer, filtration, acoustic, and light-transmission studies. The lightweight aluminum-alloy framework enables easy integration into test fixtures and prototypes, but the cellular structure requires careful handling to avoid crushing or contamination.

Positive

  • Interconnected open-pore network: The continuous open passages through the metallic cellular structure support airflow, fluid passage, and light transmission, enabling versatile use in heat-dissipation, filtration, and acoustic-control experiments.
  • Lightweight rigid aluminum framework: The aluminum-alloy cellular sheet provides a rigid porous medium that is easy to cut, bond, and integrate into laboratory fixtures, prototype housings, and layered assemblies without adding significant weight.

Trade-offs

  • Susceptible to crushing and contamination: The open-cell structure is vulnerable to permanent deformation from heavy impact or crushing, and the porous surface can easily trap contaminants if not stored in a clean, dry area.
  • Requires dimensional confirmation before use: The standard 100 × 100 × 5 mm format may not match all experimental setups; custom dimensions require consultation and feasibility review, adding lead time for non-standard applications.
