Application field of foam copper

Copper foam has many advantages, not only is it lower in production cost than nickel foam; it also has very good electrical conductivity and ductility. These two characteristics also determine that copper foam can be widely used in the manufacture of negative electrode materials for batteries; in addition, because copper foam itself has a series of advantages of metal foam, it can also be widely used in electromagnetic shielding materials and other purposes.

Copper foam is widely used as electrode framework material for new batteries due to its lower production cost and better electrical conductivity than nickel foam. In some organic chemical reactions, copper foam is also used as a catalyst to promote chemical reactions due to its large surface area. At the same time, foamed copper has very strong thermal conductivity and excellent flame retardancy; it is often used in the production of thermally conductive materials, and is widely used as heat-dissipating materials for motors and electrical appliances.

Most metal foams have very good sound insulation and are also capable of shielding electromagnetic signals. And foam copper also has this advantage. It is precisely because of this characteristic that when sound passes through the surface of foam copper, not only diffuse reflection will occur; At the same time, copper foam can also shield electromagnetic signals, and is often used as an electromagnetic shielding material. Because copper foam is non-toxic and harmless to the human body and has many internal pores, it is also used as a medical filter material by many water purification manufacturers.
