II. Main Features

Copper foam has excellent thermal conductivity and can be widely used for heat conduction and dissipation in motors, electrical appliances and electronic components.
Copper foam has superior electrical conductivity, and its application in nickel-zinc batteries and electric double-layer capacitor electrode materials is gaining significant industry attention.
Thanks to its structural characteristics and human-friendly properties, copper foam is also an excellent filtration material and water purification filter medium.

III. Application Areas

Electrode Materials: The excellent electrical conductivity allows copper foam to be widely used as skeletal electrode material for new-type batteries such as nickel-zinc batteries and electric double-layer capacitors. It has been trialed and put into batch use by several nickel-zinc battery manufacturers, and is expected to be promoted as a current collector for electric double-layer capacitor electrodes. Moreover, copper foam used as an electrode material for electrolytic recovery of copper-containing wastewater shows very broad prospects.
Catalysts: In many organic chemical reactions, people attempt to directly use copper foam with large specific surface area to replace punched copper plates as chemical reaction catalysts. Copper foam as a carrier for photocatalytic air purification has also been successfully applied.
Thermal Conduction Materials: Copper foam has excellent thermal conductivity, making it a superior flame-retardant material applied in many advanced fire-fighting equipment overseas, especially as a flame isolation device with outstanding effects. Additionally, using its excellent thermal conductivity and apparent permeability, copper foam is made into heat dissipation materials for motors and electrical appliances.
Sound Absorption and Shielding Materials: Sound waves undergo diffuse reflection on the surface of copper foam, achieving noise reduction through expansion silencing and micro-pore sound absorption principles. The shielding performance of copper is close to silver, making it an excellent electromagnetic shielding material.
Filter Materials: With excellent structural characteristics and human-friendly properties, copper foam metal products have been successfully applied as filter materials. Copper foam also shows good prospects in water purification device applications.
Fluid Pressure Buffering Materials: The dispersion and buffering effect of copper foam on fluids makes it an effective pressure reduction protection device for various pressure instruments.

How does the trade-off between pore size (5–30 PPI) and filtration efficiency affect oil impurity removal for fire-resistant oil applications?

The copper wire foam offers a pore size range of 0.1–10 mm (5–30 PPI) with 50–90% porosity and ≥98% through-hole rate, classified as medium efficiency. For fire-resistant oil filtration, smaller pores (higher PPI) improve particle capture but increase pressure drop, while larger pores (lower PPI) reduce flow resistance but may allow finer impurities to pass. The 110 mesh knitted weave and 98% open rate balance these factors for effective oil impurity removal without excessive backpressure.

Can this copper foam be integrated directly into existing battery electrode or capacitor current collector designs given its 0.1–0.8 g/cm³ bulk density and 0.01–10 mm filament diameter?

Yes, the copper foam's bulk density of 0.1–0.8 g/cm³ and filament diameter of 0.01–10 mm make it suitable as a skeletal electrode material for nickel-zinc batteries and electric double-layer capacitor electrodes, as stated in the application areas. Its ≥98% through-hole rate and excellent electrical conductivity support current collection and ion transport, but integration requires verifying compatibility with specific electrolyte chemistries and mechanical assembly constraints, as the foam is supplied in 200×200×1 mm sheets with custom sizing available.

What handling or storage precautions are required to prevent oxidation or structural degradation of the 1 mm thick copper wire foam with 50–90% porosity?

The product is acid and alkali resistant, but copper is prone to surface oxidation in humid or corrosive environments. The 1 mm thickness and high porosity (50–90%) increase surface area exposure, so storage in a dry, inert atmosphere or with desiccants is recommended to maintain electrical and thermal conductivity. No specific handling instructions are provided in the source, but the material's knitted weave and 0.01–10 mm filament diameter suggest careful handling to avoid deformation or tearing during cutting or installation.

Assessment

Atomfair's copper wire foam sheet (200×200×1mm) delivers high permeability (≥98% open area) and tunable pore structure (5-30 PPI) for filtration of fire-resistant oils, while its thermal and electrical conductivity extend utility to heat dissipation and battery electrode applications.

Positive

High through-hole rate and porosity: With ≥98% through-hole rate and 50-90% porosity, this copper foam provides excellent fluid permeability for efficient filtration and heat dissipation.
Dual thermal and electrical conductivity: The material's superior thermal and electrical conductivity enables its use as both a heat spreader in electronics and a skeletal electrode material in nickel-zinc batteries and capacitors.

Trade-offs

Thin profile mechanical limits: The 1mm thickness combined with high porosity may reduce structural rigidity under high differential pressure or flow-induced vibration, requiring careful mounting.
Application-specific fluid compatibility: This foam is designed for fire-resistant oil impurity removal; compatibility with other fluids or operating conditions must be verified by the user.
