The thermodynamics and kinetics of internal oxidation of Cu-Al alloy were investigated in the present paper. The thermodynamic calculation results show that, the behavior of Cu-Al alloy internal oxidation is feasible in thermodynamics. The thermodynamic area chart of oxidation of the Cu-Al alloys was obtained. The figure of oxidation weight gain of Cu-1.0%Al alloy was obtained by the oxidation experiment. Results show that the temperature range of Cu-1.0%Al alloy rapidly internal oxidation is from 700 ℃ to 900 ℃.The conductivity, hardness and density of the copper-based composite are increased with the rise of internal oxidation temperature. When the tempera-ture is above 900℃, changes of properties are towards stability.
