What are the key technical specifications of ATOMFAIR copper foam that make it suitable for thermal and electrical applications?

Atomfair copper foam offers porosity of 60-98%, a through-hole rate of ≥98%, and a PPI range of 5-130. It has a thermal conductivity greater than 6 W/(m²·K) and mechanical strength of at least 2.5 MPa. These properties make it effective for heat dissipation, battery electrodes, and EMI shielding.

Can copper foam be used as a current collector for electric double-layer capacitors?

Yes, copper foam has been trialed and put into batch use by several manufacturers as a skeletal electrode material for nickel-zinc batteries and electric double-layer capacitors. The source indicates it is expected to be promoted as a current collector for electric double-layer capacitor electrodes, with broad prospects in electrolytic recovery of copper-containing wastewater.

How does copper foam provide both electromagnetic shielding and sound absorption?

Copper foam achieves noise reduction through diffuse reflection of sound waves on its surface, utilizing expansion silencing and micro-pore sound absorption. For EMI shielding, copper's performance is close to silver, making it an excellent electromagnetic shielding material. The high porosity and interconnected structure contribute to these multifunctional properties.

Assessment

This copper foam variant offers 60–98% porosity with ≥98% through-hole rate and thermal conductivity above 6 W/(m²·K), making it viable for electrode, thermal, and filtration applications, though its low tensile strength (5–18 kPa) requires careful handling and structural support in load-bearing uses.

Positive

High porosity and through-hole integrity: Porosity ranges from 60% to 98% with a through-hole rate of at least 98%, enabling efficient fluid flow, filtration, and electrode surface area for battery and capacitor applications.
Superior thermal and electrical conductivity: Thermal conductivity exceeds 6 W/(m²·K) and electrical conductivity is explicitly highlighted, supporting use in heat dissipation components and as current collector or electrode skeletal material.

Trade-offs

Low tensile strength requires handling care: Tensile strength is only 5–18 kPa, indicating the foam is mechanically fragile and susceptible to deformation or tearing during cutting, mounting, or operation; structural reinforcement may be needed.
Porosity range affects performance consistency: With porosity spanning 60–98% and pore size 0.1–10 mm, the actual material properties vary significantly by selected variation; buyers must specify and verify the exact porosity and pore size for their intended application.
