Various properties of aluminum foam can be obtained by changing the base aluminum alloy. In this study, we attempted to fabricate a two-layer aluminum foam with the upper layer of commercially purity aluminum A1050 foam and the lower layer of Al-Si-Cu aluminum alloy ADC12 foam by using an optical heating device that can heat from both the upper and lower sides. It was shown that both precursors can be foamed and joined, and a two-layer A1050/ADC12 foam can be fabricated.

Side views of the resulting two-layer aluminum foam, an X-ray CT images of a longitudinal section near the center of the sample, and the time t from the start of heating the precursor to the end of the heating process for heating and foaming two precursors with a gap between them.
