Open-Cell Aluminum Foam 3–4 mm 100×100×10 mm ATOMFAIR®

Open-Cell Aluminum Foam, 3–4 mm Pore Size, 100 × 100 × 10 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 10 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.

How do the porosity (70–90%) and open-cell rate (55–65%) differ, and why are both specified for this aluminum foam?

Porosity measures the total void fraction including both open and closed cells, while open-cell rate specifically quantifies the fraction of interconnected pores that allow fluid or light passage. Both parameters are provided because the foam's performance in applications such as filtration, heat transfer, or acoustic control depends on the interconnected network (open-cell rate) as well as the overall void volume (porosity). The typical ranges indicate that a significant portion of pores are open, but some closed cells may exist within the aluminum-alloy framework.

Can this 10 mm thick open-cell aluminum foam be integrated into a layered assembly with other porous media without significant compression?

The foam is a rigid aluminum-alloy cellular sheet with a nominal thickness of 10 mm and a sheet size of 100 × 100 mm. Its rigid framework resists compression under moderate loads, but heavy impact or crushing should be avoided as stated in the handling guidelines. For layered assemblies, ensure the foam is not subjected to forces that could deform the pore structure; custom dimensions are available upon consultation if the standard format does not fit the assembly design.

What storage and handling conditions are recommended to preserve the pore structure of this aluminum foam?

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 help maintain the interconnected open-pore network and the specified 3–4 mm pore size range.

Assessment

This open-cell aluminum foam sheet (3–4 mm pore size, 100 × 100 × 10 mm) provides a rigid, interconnected porous metallic 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 integration into test fixtures and layered assemblies, but the cellular structure is susceptible to crushing under heavy impact and requires clean, dry storage to prevent contamination.

Positive

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

Trade-offs

Susceptible to crushing under impact: The cellular surface must be protected from heavy impact and crushing forces during handling and storage, as the open-cell structure can deform permanently under mechanical load.
Requires clean dry storage conditions: Contamination from dust, moisture, or particulates can block the open pores and alter the material's flow or filtration performance, necessitating storage in a clean, dry environment.
