Copper Foam

Product Information

Copper foam is a rigid, three-dimensional network of interconnected copper ligaments that form cells with open pores.  Copper Foam contains completely solid ligaments (as opposed to sintered or hollow ligaments) which makes it stronger and more thermally conductive. Its properties are fully customizable, which allows its performance characteristics to be optimized for a broad range of applications. It is commonly used in applications that benefit from very high thermal conductivity and surface area, and from the nature-mimicking morphology of the rigid cellular structure.

Copper Foam Applications 

* Electrode material

Copper foam has excellent electrical conductivity, which makes it widely used as electrode frame materials for new batteries such as nickel-zinc batteries and electric double-layer capacitors.

* Catalyst

Copper foam acts as a catalyst in many organic chemical reactions, such as directly replacing perforated copper plates as a chemical reaction catalyst. Foamed copper has also been successfully used as a carrier for photocatalytic air purification.

* Thermally conductive materials

Copper foam has excellent thermal conductivity, which makes it a flame retardant material with excellent performance. In addition, people use copper foam to make heat dissipation materials for motors and appliances.

* Silencing and shielding materials

Copper foam is a very good silencing material. Sound waves will be diffusely reflected on the surface of the foamed copper, and the sound absorption effect is achieved through the principles of material expansion and microporous noise elimination. Cooper foam is also an excellent electromagnetic shielding material, and its shielding performance is close to silver.

* Filter material

Copper foam is basically harmless to the human body, which makes it successfully used as a medical filter material. At the same time, the application of copper foam in water purification devices has a good future.

* Fluid pressure buffer material

The dispersing and buffering action of the copper foam on the fluid makes it an excellent pressure reducing protection device for various pressure gauges.

Packing of Copper Foam

Standard Packing:

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.

ATTs’ Copper foam is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
