Abstract
The invention relates to a process for producing metal foam and to a metal body produced using this process. The object is achieved by a process for producing metal foam by adding a blowing agent to a metal melt, wherein the metal melt is introduced into the die cavity of a metal die-casting machine and is foamed using a blowing agent which releases gases and is solid at room temperature.
