Main Features

(1) Copper foam has excellent thermal conductivity, can be widely used in motors/electrical appliances and electronic components of the thermal conductivity of heat dissipation.

(2) Copper foam has excellent electrical conductivity, and its application in electrode materials of nickel-zinc batteries and double-layer capacitors is also being emphasized by the industry. industry's attention.

(3) Due to its structural properties and harmlessness to human body, copper foam is also an excellent material for medical filtration and water purification filtration. water purification filtration material.

Application Fields

(1) Electrode material. Excellent conductive properties of copper foam can be widely used in nickel-zinc batteries, double layer capacitors and other new battery electrode skeleton materials, copper foam has been a number of nickel-zinc battery manufacturers to try and put into batch use, while copper foam is expected to be used as a double layer capacitor electrode electrode collector to gain popularity; in addition, copper foam as electrolytic recycling of copper-containing wastewater electrode materials, also has a very broad prospect of the use. Prospect.

(2) Catalyst. In many organic chemical reactions, people try to directly use copper foam with a large surface area instead of perforated copper, as a catalyst for chemical reactions; copper foam as a photocatalytic air purification carrier, has also been more successful applications.

(3) Thermal conductivity materials. Copper foam has excellent thermal conductivity, making it a flame retardant material with excellent performance, which has been applied in many advanced fire-fighting equipment in foreign countries, especially as flame isolation equipment with excellent results; in addition, people utilize copper foam's excellent thermal conductivity and apparent permeability to make heat dissipation materials for electric motors and electrical appliances.

(4) Sound deadening and shielding materials. Sound waves in the copper foam surface diffuse reflection, and through the expansion of the sound, microporous sound dissipation and other principles, to achieve the effect of sound damping; copper shielding properties and silver close to the performance of an excellent electromagnetic shielding materials.

(5) Filter material. Excellent structural properties and the basic harmless to the human body of the foam metal copper products, as a medical filtration materials, has also been successfully applied; at the same time, the foam copper in the water purification device application also has a better future.

(6) Fluid pressure buffer material. Foam copper on the fluid dispersion and buffer effect, so that it as a variety of pressure instrumentation pressure reduction protection device, with excellent results. There are various thicknesses (1MM*50MM) and different specifications for customers to choose.

Copper foam is a new type of multifunctional material with a large number of connected or disconnected holes uniformly distributed in a copper matrix. Copper foam has good conductivity and ductility, and the preparation cost is lower than that of nickel foam, and the conductivity is better, so it can be used for the preparation of battery negative electrode (carrier) materials, catalyst carriers and electromagnetic shielding materials. In particular, copper foam is used in batteries as the substrate material for electrodes, has some obvious advantages, but due to the corrosion resistance of copper is not as good as nickel, thus limiting some of its applications.
