Abstract: Quasi-static compression tests, tensile tests and bending tests were carried out to study the mechanical properties of the closed-cell aluminum foam in the porosity range of 72%-93%, which was manufactured by melt transferring-foaming process.Results indicate that the compression curve of aluminum foam, including linear elastic zone plateau zone and densification zone; the compress behavior is influenced by the ratio of height (H)/extent (D) of specimens. The plateau stresses are roughly constant with increasing strain until the densification occurs, when H/D is less than 1.4. The stress plateau is serrated, as is typical of brittle foam:the serrations correspond to fracture of cell walls, when H/D is greater than 1.4; and it emerges shearing zone, which is 25°-45° with the loading axis in the middle of samples. The procedure of Al-foam under tensile and bending presents that the stress rapidly increases, then flutteringly fades when it reach up to the peak stress. There is not visible yielding zone before fracture finally. The compressive flow strength R_pl, tensile yield stress R_UTS and bending yield stress R_f all raise with increasing density.
