Open-Cell Aluminum Foam, 3–4 mm Pore Size, 100 × 100 × 8 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 8 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.

The open-cell aluminum foam sheet requires storage in a clean, dry environment to prevent contamination and structural damage. The cellular surface is susceptible to crushing and deformation from heavy impact, necessitating careful handling during integration.

  • Storage Environment: Store the sheets in a clean, dry area to avoid contamination and moisture exposure.
  • Impact Protection: Protect the cellular surface from heavy impact, crushing, and contamination during handling and storage.
  • Pre-Use Inspection: After delivery, check the package condition, sheet dimensions, and visible pore structure before cutting, bonding, or installing.
  • Operating Environment Consideration: Consider the intended medium, mounting method, and surrounding operating conditions when integrating the material.

These steps outline the recommended handling and inspection procedures for open-cell aluminum foam sheets. Proper execution maintains the material's structural integrity and performance in research assemblies.

  1. Inspect Upon Delivery
    Inspect the package condition, sheet dimensions, and visible pore structure immediately after delivery.
  2. Store in Clean, Dry Area
    Store the sheets in a clean, dry area, protecting the cellular surface from heavy impact, crushing, and contamination.
  3. Verify Before Integration
    Confirm the sheet dimensions and pore structure before cutting, bonding, or installing the material.

How does the 55–65% open-cell rate influence the trade-off between fluid permeability and structural rigidity in this aluminum foam?

The open-cell rate of 55–65% indicates that over half of the volume consists of interconnected void space, which promotes fluid flow and light transmission but reduces the load-bearing cross-section. The aluminum-alloy framework provides rigidity, but the high porosity (70–90%) means the foam is best suited for applications where flow or surface area is prioritized over mechanical strength.

Can this open-cell aluminum foam be integrated into a filtration assembly for gas or liquid applications without additional surface treatment?

Yes, the interconnected open-pore network and continuous passages allow direct use in gas or liquid filtration assemblies as stated in the application scope. However, the aluminum alloy may require compatibility checks with the specific fluid chemistry to avoid corrosion. The standard sheet size of 100×100×8 mm can be cut to fit, but cutting may expose raw edges that could shed particles.

What storage and handling precautions are necessary to preserve the pore structure of the 8 mm thick aluminum foam sheets?

Store the sheets in a clean, dry area and protect the cellular surface from heavy impact, crushing, and contamination as specified in the handling instructions. After delivery, inspect the package condition, sheet dimensions, and visible pore structure before cutting, bonding, or installing to ensure the 3–4 mm pores remain unobstructed.

This open-cell aluminum foam sheet (3–4 mm pore size, 100 × 100 × 8 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 control, and light-transmission studies. The lightweight aluminum-alloy framework facilitates integration into test fixtures and prototype assemblies, though the open-cell structure requires careful handling to avoid crushing and 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 foamed aluminum alloy provides a rigid yet lightweight porous medium that can be easily cut, bonded, or integrated into laboratory fixtures and prototype assemblies without adding significant mass.

Trade-offs

  • Susceptible to crushing and contamination: The open-cell structure is vulnerable to heavy impact and particulate ingress; storage in a clean, dry area and protection from mechanical compression are required to maintain pore integrity.
  • Fixed sheet dimensions limit direct fit: The standard 100 × 100 × 8 mm format may not match all experimental setups; dimensional customization requires consultation and feasibility review, adding lead time for non-standard applications.
