Characteristics and application of foam copper

Heat Conduction

Copper foam has excellent thermal conductivity and apparent permeability, and has been made into heat-dissipating motors, electrical appliances, etc. In addition, copper foam has become an excellent flame retardant material due to its good thermal conductivity. Fire fighting equipment has been applied, especially as a flame insulation device, the effect is better.

Electrode

Due to its good electrical conductivity, copper foam can be widely used in electrode skeleton materials of new batteries, such as nickel-zinc batteries, electric double layer capacitors, etc. Copper foam is expected to be popularized as electrode current collectors of electric double layer capacitors; Copper can also be used as an electrode material for electrolytic recovery of copper-containing wastewater, which has broad application prospects.

Impact Resistance

When the external impact acts on the foamed copper composite material, the interlaced multi-direction absorbs a large amount of kinetic energy for the wire diameter, resulting in three stages of elastic deformation, plastic deformation and densification. Thermal diffusion and absorbing vibration damping effect.

Filter

The structural characteristics of foamed copper products are basically harmless to the human body, and they have been successfully used in medical filter materials; at the same time, foamed copper products also have good application prospects in water purification equipment.

Catalytic

At present, in many organic chemical reactions, attempts are made to directly replace the punched copper plate with copper foam with a larger specific surface as a catalyst for chemical reactions, and copper foam as a carrier for photocatalytic air purification is also relatively successful.

Muffler Shield

The sound waves are diffusely reflected on the surface of the copper foam, and the noise reduction effect is achieved through the principles of expansion noise reduction and microporous noise reduction. The shielding performance of copper is close to that of silver, and it is an electromagnetic shielding material with excellent performance.
