Different production methods are divided into two groups of liquid state and powder method based on the initial state of the metal. The aim of this study is to provide a new method for the production of open cell aluminum foam with Sodium Chloride spacer. Two different types of aluminum alloy with different fluidity were used to produce foam with this method. Pressure tests were performed to show the compressive behavior of aluminum foams. The results showed that the behavior of foams produced by this method is the same as the outcomes of other papers. In different densities, the behavior of the soft foam was the same, but the stress was higher in the same displacement for higher densities. In the same density for the two different alloys, the axial strength of the A332 alloy was higher, but in contrast the soft foam is a good energy absorber. Young's modulus for two types of alloys with identical densities was 1.45 GPa for the A332 alloy and 1.11 GPa for the 1067 alloy. The amount of energy efficiency decreased by densifying the foam.
