Laboratory Open-Cell Copper Foam, 20 PPI, 100 × 200 × 20 mm, 1/5 pcs
Research-grade laboratory product
Product Overview

Open-cell copper foam with 20 PPI provides an interconnected porous-metal structure in a 100 × 200 × 20 mm sheet. Its nominal pore pitch is approximately 1.27 mm, offering a clearly defined cellular specification for laboratory selection and engineering integration.

The material is a foamed copper sheet with a stated porosity of 50–80%, a through-pore rate of at least 98% and a bulk-density range of 0.1–0.8 g/cm³. This combination preserves the continuous open network required for high internal surface exposure while retaining the thermal and electrical characteristics associated with the copper framework.

The open copper network can be evaluated for electrode frameworks and current-collection structures, catalyst-support assemblies, heat-transfer and heat-dissipation components, filtration and water-purification media, acoustic attenuation and electromagnetic-shielding structures, and fluid-pressure buffering devices. Selection should be based on PPI, sheet dimensions, thickness, package quantity and the intended integration method.

Application Scope

Suitable for laboratory and engineering evaluations that require a 20 PPI open copper network in a 100 × 200 × 20 mm format. Relevant uses include nickel-zinc battery and electric-double-layer-capacitor electrode structures, copper-containing wastewater recovery electrodes, catalyst and photocatalytic air-purification carriers, motor and electronic-component heat-transfer parts, filtration and water-purification media, acoustic attenuation, electromagnetic shielding and pressure-instrument buffering components.
SELECTION GUIDANCE: Confirm PPI, nominal pore pitch, porosity requirement, through-pore rate, sheet length and width, thickness, bulk-density range and required quantity before quotation. Confirm any application-critical pore geometry and integration requirements before ordering.
HANDLING & INSPECTION: Store the sheets in a clean, dry area and protect the open 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, PPI and estimated quantity.

Store the copper foam sheet in a clean, dry area to prevent contamination and physical damage. Protect the open-cell structure from heavy impact, crushing, and contamination during handling and storage.

  • Storage Conditions: Store the sheets in a clean, dry area and protect the open cellular surface from heavy impact, crushing and contamination.
  • Pre-Use Inspection: After delivery, check the package condition, sheet dimensions and visible pore structure before cutting, bonding or installing the material.

How does the 20 PPI pore density affect the trade-off between pressure drop and filtration efficiency for this open-cell copper foam?

The 20 PPI specification yields a nominal pore pitch of approximately 1.27 mm, resulting in larger open pores compared to finer PPI grades (e.g., 0.1 mm at 100 PPI). This larger pore size reduces fluid flow resistance but also lowers the ability to capture fine particulates below the pore size range. The through-pore rate of ≥98% ensures an interconnected network, making this foam suitable for applications where minimizing pressure drop is prioritized over high-filtration precision.

What are the critical integration requirements for using this copper foam as a heat-transfer component in electronic assemblies?

For thermal management, the 20 mm thick open-cell copper foam (20 PPI, 50–80% porosity) provides high internal surface area but requires good thermal interface contact to the heat source. The handling guidance specifies that the cellular surface must be protected from heavy impact or crushing before cutting, bonding, or installation. Bonding methods must maintain the continuous copper framework to preserve thermal conductivity, and custom dimensions are available to match specific heat-sink geometries.

What storage and handling conditions are recommended to preserve the structural integrity of this 20 PPI copper foam?

Store the copper foam sheets in a clean, dry area to minimize moisture-induced oxidation of the copper framework. The open-cell structure must be shielded from heavy impact, crushing, and contamination to preserve the interconnected pore network and the stated through-pore rate of ≥98%. After delivery, inspect package condition, sheet dimensions, and visible pore structure before any cutting, bonding, or installation to ensure the material meets the required porosity range of 50–80%.

This 20 PPI open-cell copper foam in a 100 × 200 × 20 mm sheet offers a high through-pore rate (≥98%) and a porosity range of 50–80%, providing a well-defined cellular network for electrode, catalyst-support, and thermal-management evaluations. The copper framework supports electrical and thermal conduction, while the bulk density of 0.1–0.8 g/cm³ indicates a lightweight, porous structure suited for laboratory integration.

Positive

  • Interconnected open-pore network: The 20 PPI cellular structure with a nominal pore pitch of 1.27 mm and a through-pore rate of at least 98% ensures high internal surface exposure and continuous fluid pathways, which is critical for electrode, catalyst, and filtration applications.
  • Tunable porosity and density range: With a porosity of 50–80% and bulk density of 0.1–0.8 g/cm³, the foam provides a low-mass, high-surface-area copper network that can be matched to specific thermal management or electrochemical performance requirements.

Trade-offs

  • Fragile surface requires careful handling: The open cellular structure is susceptible to deformation from heavy impact, crushing, or contamination, necessitating clean, dry storage and careful handling during cutting, bonding, or installation to preserve pore integrity.
  • Fixed dimensions require pre-order confirmation: This product is supplied in a standard 100 × 200 × 20 mm sheet with confirmed PPI and porosity; custom dimensions are only available upon consultation, so application-specific sizing must be verified before ordering to avoid integration mismatches.
