Open-Cell Aluminum Foam 3–4 mm Pore 8 mm Sheet ATOMFAIR®

Open-Cell Aluminum Foam, 3–4 mm Pore Size, 200 × 200 × 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 200 × 200 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 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.

What is the difference between porosity and open-cell rate in this aluminum foam, and how do they affect fluid flow and mechanical integrity?

Porosity (70–90% typical) refers to the total void fraction, while open-cell rate (55–65% typical) indicates the proportion of interconnected pores that allow continuous fluid passage. A higher open-cell rate improves flow permeability but may reduce the load-bearing capacity of the metallic framework. These parameters are explicitly stated for the AF-O34-20-T08 model to help users balance passage geometry against structural requirements.

Can this open-cell aluminum foam be used for both gas and liquid filtration applications?

Yes, the interconnected open-pore network supports both gas and liquid filtration assemblies, as listed in the typical applications. The 3–4 mm pore size and 55–65% open-cell rate allow fluid passage, but the aluminum alloy framework may not be compatible with corrosive or high-temperature media. Users should confirm the intended operating environment and chemical compatibility before integration.

What are the recommended storage and handling procedures to prevent damage to the cellular structure?

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 handling and inspection guidance to preserve the open-cell geometry.

Assessment

This open-cell aluminum foam sheet (200 × 200 × 8 mm, 3–4 mm pore size) provides a rigid, lightweight porous medium with interconnected passages suitable for heat-transfer, filtration, acoustic, and light-transmission studies. The 70–90% porosity and 55–65% open-cell rate define its flow and surface-contact behavior, while the aluminum-alloy framework enables straightforward integration into lab fixtures and prototypes.

Positive

Interconnected open-pore network: The continuous open passages through the metallic cellular structure support airflow, fluid passage, and light transmission, enabling multipurpose use in heat-transfer, filtration, and acoustic experiments.
Lightweight rigid aluminum framework: The foamed aluminum alloy provides a mechanically stable porous medium that can be cut, bonded, or integrated into test fixtures and prototype assemblies without excessive weight.

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 open-cell structure is mechanically fragile under point loads.
Fixed sheet dimensions limit direct fit: The standard 200 × 200 × 8 mm format may not match all experimental setups; dimensional customization requires consultation and feasibility review before ordering.
