The present application provides a method for manufacturing a metal alloy foam. The present application can provide a method for manufacturing a metal alloy foam, which is capable of forming a metal alloy foam comprising uniformly formed pores and having excellent mechanical properties as well as the desired porosity, and a metal alloy foam having the above characteristics. In addition, the present application can provide a method capable of forming a metal alloy foam in which the above-mentioned physical properties are ensured, while being in the form of a thin film or sheet, within a fast process time, and such a metal alloy foam.
A method for manufacturing a metal alloy foam comprising a step of sintering a green structure comprising a metal component, which comprises a first metal having a relative magnetic permeability of 90 or more and a conductivity at 20° C. of 8 MS/m or more and a second metal different from the first metal.
A metal alloy foam comprising an alloy of a first metal having a relative magnetic permeability of 90 or more and a conductivity at 20° C. of 8 MS/m or more and a second metal different from the first metal, and having a porosity in a range of 40% to 99% and a tensile strength of 2.5 MPa or more.
