The aluminum base alloy is a candidate of the liner material of a high-pressure-hydrogen gas container installed in a fuel cell vehicle. However, because the inner surface of the liner material is exposed to high-pressure hydrogen, the possibility of hydrogen embrittlement should be taken into account. In the previous study, the behavior of hydrogen in a rolled sheet of 6061 and 7075 aluminum alloys as investigated by the hydrogen microprint technique. Since extrusion is thought to be more effective than rolling as a manufacturing process of the liner. Therefore, the behavior of hydrogen in 6061 and 7075 aluminum alloy extrusions was investigated in this study. As a result, hydrogen desorption was seen from the second phase particles in the 6061 alloy, but not in the 7075 alloy.
