structure of closed-cells due to the simultaneous occurrence of the melting of the metal and thermal decomposition of the blowing agent with the release of a gas (e.g. H 2). The liquid foam is then cooled in air, resulting in a solid foam with closed cells and with a very thin dense skin that improves the mechanical properties of these materials. Aluminium Foam Properties and applications Materials HubOpen-cell and closed-cell foams can be created in one of two ways. The first method injects gas into metallic melts and as gas bubbles through the molten metal, a foam is created, which is then removed and allowed to cool.
