The authors propose a method to fabricate porous metals with high strength in this paper. Pieces of matrix metal and space‐holder metal are deformed together by bulk forming for solid‐phase bonding. From the bonded composite, only the space‐holder metal is removed. If the deformation and the removal are conducted at cold or warm region, ‘wrought' high‐strength porous metal can be obtained. In this study, using aluminum as space holder, two types of porous copper with one‐dimensional pores, i.e., lotus‐type and honeycomb‐type rods, have been successfully fabricated by cold extrusion followed by chemical leaching. Both the porous coppers fabricated show higher specific yield strength than a conventional porous metal.
