Here today we list a hot seller items: Copper Foam Sheet, 500x1000mm, 10mm Толщина, 40PPI .

Specification Breakdown:

-Dimensions: 500 mm x 1000 mm (approx. 19.7″ x 39.4″). This is a large, flat sheet, which suitable for cutting to size for various applications.
-Толщина:10 mm. This provides a substantial depth for fluid flow, filtration, or heat exchange while maintaining structural integrity.
-PPI (Pores Per Inch):40. This is a measure of the foam’s pore density.
40 PPI is considered a medium-fine pore structure. It offers an excellent balance between high surface area (good for heat transfer and catalysis) and relatively low flow resistance.
For comparison: 10 PPI is very open and porous, while 80-100 PPI is extremely fine and dense, creating much higher flow resistance.
-Материал: Pure 99.95% Copper.
-Key Properties: Excellent thermal conductivity, good electrical conductivity, antimicrobial, and malleable.
-The foam will have a very high surface area-to-volume ratio due to its porous structure.

1. Extremely High Surface Area: The interconnected porous network creates a massive surface area within a compact volume, which is crucial for efficient heat exchange and chemical reactions.
2. Excellent Thermal Conductivity:Copper is one of the best thermal conductors. The foam structure allows for rapid heat dissipation from the solid matrix to a fluid (air or liquid) passing through it.
3. Low Density & Lightweight: Despite being metal, the foam is mostly air (typically 85-98% porosity), making it much lighter than a solid copper block of the same dimensions.
4. High Permeability & Mixing:The open cells allow fluids to pass through easily, while the tortuous path promotes turbulent flow and excellent mixing.
5. Antimicrobial Properties:Copper ions are naturally biocidal, making this foam suitable for applications requiring hygiene, such as air or water filtration.

-Heat Exchangers & Heat Sinks:Ideal for compact, high-efficiency heat exchangers. Forced air or liquid coolant is pushed through the foam, transferring heat incredibly effectively. Used in aerospace, electronics cooling (e.g., for high-power LEDs or CPUs), and advanced HVAC systems.
-Catalyst Support: The high surface area provides an excellent substrate for catalytic coatings. Used in chemical reactors, automotive catalytic converters (in R & D), and pollution control systems to facilitate chemical reactions.
-Flame Arrestors & Flashback Prevention:*Placed at the end of a pipe, it can quench a flame propagating through a flammable gas mixture, preventing an explosion.
-Acoustic Absorption & Dampening: Effective at absorbing sound waves, particularly in mid-to-high frequency ranges, for industrial noise control.
-Fluid Filtration & Separation:Can be used as a filter for hot gases or corrosive liquids, or as a coalescing filter to separate mist from air.
-Battery Electrode Structures (R & D): В advanced battery designs, the conductive, porous structure can be used as a 3D current collector to improve power density.
-EMI Shielding: Provides effective electromagnetic interference shielding for sensitive electronic equipment, with the added benefit of thermal management.
