Abstract
Aluminium metal foam has a cellular structure. It's lightweight with these unique physical and mechanical properties and widely used in structural and functional applications. This paper's studies show the possible ways to produce Aluminium metal foam and its different properties and, based on that, the field it has applications. During the studies, it is observed that the Aluminium metal foam can develop in two ways: solid route and liquid route, after acquiring unique properties, such as light in weight to strength, suitable acoustic properties, and shock and energy absorption capabilities. The application will be selected based on properties and open or closed pore cells obtained in Aluminium metal foam. The significant finding from the review is that Aluminium metal foam has broad applications. However, the main lacunas that are still Aluminium metal foam are commercially not used because it is challenging to get good properties such as attaining uniform distribution and percentage of porosity in the prepared foam sample and uniform pore size. Another critical factor is that the cost will be high if the liquid or solid route develops the metal foam. So powder metallurgy process is the best method to produce metal foam to get better surface integrity and a proper network connection between each pore.
