Abstract: Aluminium metal foams nowadays are popularly used because of their unique feature of high stiffness concerning low density in the order of 10-15% of the bulk Aluminium material. In this paper, Aluminium metal foam is developed using the powder metallurgy technique. The elements used in the composition are Aluminium metal powder and a foaming agent as a wax powder (3-9%). The porosity is calculated using the Archimedes principle and achieved a good percentage of porosity in the specimen with a blowing agent as wax powder and achieved maximum porosity of 60.41%. The Microstructure study has been done on the prepared specimens to check the uniform distribution of porosity on the entire specimen and to check if any foreign chemical factor is incorporated. It is found that there is no adequate result in the prepared specimen.
