Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method for producing a member made of a foamed aluminum alloy, which can be applied to aluminum alloys with various melting points regardless of the alloy compositions, and inexpensively produces the member of the foamed alloy having superior recycability. SOLUTION: This production method comprises the steps of: heating the aluminum alloy to melt it; adding a mixture of magnesium carbonate and calcium carbonate into the molten metal to foam it; and rapidly solidifying the foamed molten metal. Alternatively, the production method comprises the steps of: adding the mixture of the carbonates into the molten metal; then, solidifying the molten metal without foaming it; pulverizing it into pellets; forming the pellets into a precursor as needed; and then, heating the precursor in a mold to foam it.
