In order to bond the aluminum foams by foaming bonding, the oxide film on the surfaces of the foams has to be removed. A flux is widely used for the aluminum brazing-bonding to remove the oxide film. In this study, the effect of the surface treatment by the flux on the bonding strength of the specimen bonded by the foaming bonding is investigated. A commercial flux was applied to bonding surfaces of two aluminum foams. An aluminum precursor with low melting point was put between the aluminum foams and it was heating and foaming. The bonding strength of the bonded specimen was evaluated by using 4 point bending test. The bonding strength of the bonded specimen with flux applied is 30 % higher than that without flux applied. However, the bending strength of the bonded specimen varies widely. This is because that a part of the cell wall of the aluminum foams was melted and broken.
