Abstract:Aluminum metal foam has wide applications for lightweight construction has become an attractive research field. In this review paper, the various possible methods for Aluminium metal foams production and other cellulose metallic structures are studied. According to the state of matter the different production processes are classified into three ways solid, liquid and gaseous. Metal foams have a unique property such as light weight in combination with higher compression strength, lower specific weight, high stiffness and better energy absorption quality. Production of metal foams is a very difficult task because of the simultaneous occurrence of solid, liquid and gaseous phase's at different temperatures. There are number of technologies and methods of manufacturing foamed metals are available but still the foamed metal suffers from deficiencies and non-uniformities. To improve the foam quality, it is necessary to study and understand the foam stability of liquid metals, which will help production techniques of foam metals more reliable and producible. In this review finds the best suitable method for production of aluminum metal foam for mechanical application. It has been experimentally confirmed that aluminum metal foams produced by the Powder Metallurgy method present high pore connectivity hence there is a chances to get good result when we will do the analysis over application.
