Behaviour of copper and aluminium oxidation by nonequilibrium electrolysis was investigated. Influence of synthesis conditions (kind of electrolyte, concentration of its solution, synthesis temperature) on metal oxidation was estimated. Oxidation rate depends on synthesis conditions, but it is limited to metal nature. Stability both metal and products of metal oxidation to electrolyte ions is the main condition of synthesis of metal oxides. Sodium chloride is the best electrolyte according to this condition. Formation of intermediate copper-aluminium species is the reason of significant increase of copper oxidation rate. According to X-ray analysis copper (I) oxide and semi-crystallized boehmite are only produced during nonequilibrium electrolysis irrespective of synthesis conditions. Depending on concentration of electrolyte solution and temperature there is opportunity to receive copper-aluminium oxide system that contain up to 25 wt % CuO.
