Extremely low levels of hydrogen concentration in molten aluminum cast alloy has been required for the production of high-performance alloys. AC2B (Al-5.0〜7.0mass%Si-2.0〜4.0mass%Cu) alloy, which is one of the typical aluminum casting alloys, is mainly used for the automobile industry. It is expected that vacuum treatment of molten alloy can lead to small oxidation loss of metal and excellent hydrogen removal. In order to clarify the hydrogen solubility and removal mechanism of vacuum degassing, hydrogen concentrations of AC2B alloy after hydrogen injection at the temperature of 973 to 1123K and vacuum treatment of 5×102Pa at 1023K were investigated in this study. It was found that hydrogen solubility of molten AC2B aluminum alloy can be described by the following equation: 1 4891 log(S(cm3 / 100 g-Al)) = log(PH 2 (mmHg)) − + 3.165 2 T (K).
