Porous copper foam is a new type of porous structure metal material with a certain number and size pore size and a certain porosity. The material has the characteristics of small bulk density, large specific surface area, good energy absorption, high specific strength and specific rigidity. The throush-hole body has strong heat exchange and heat dissipation capabilities, good sound absorption performance, and excellent permeability. Foam metal with different parameters and indicators can be adapted to a variety of different functional and structural uses, and can have both functional and structural attributes.
