Copper foamed has good mechanical properties and processing properties, excellent electrical and thermal conductivity, and has a large number of three-dimensional three-dimensional porous structures inside the material. At the same time, it has the alkali corrosion resistance, good tensile strength and ductility of metal copper itself. And has better electromagnetic shielding and noise reduction shock absorption. It can be widely used in heat dissipation and heat exchange materials of electronic components such as cpu, graphics cards, LEDs, phase change energy storage materials, buffering and shock absorption structural materials, lithium ion or fuel cell electrode materials, noise reduction materials, electromagnetic shielding materials, building materials, Various primary filters, catalysts and carriers, etc.
