As a new type of multifunctional material, copper foam is believed to be unknown to many people. In fact, copper foam mainly uses copper as the base, in which a large number of connected or disconnected holes are evenly distributed, thus producing a new multi-functional material of copper foam.
1. Advantages of copper foam
Copper foam itself 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.
2. Application field of copper foam
At present, most of the metal foams are often affected by the base material in the production process. Poor performance, then the characteristics of copper foam can make it mainly used as a new material in which fields?
Compared with nickel foam, copper foam has a lower production cost and better electrical conductivity; therefore, it is widely used as an electrode framework material for new batteries. 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.
3. Copper foam sound insulation and degaussing, non-toxic and harmless
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 the sound will not only diffusely reflect through the surface of the foam copper, but also achieve the effect of noise reduction through the reasons of expansion noise reduction and microporous noise reduction. 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.
