In a regenerable electric capacitor, particularly for a.c. voltage applications, the metal coatings consist of an alloy of aluminum and a metal whose oxides possess a specific resistance rho <109 OMEGA cm. Alloy metals are preferably copper or zinc, and maganese, tin, silver, chromium, iron or lead are also suitable. With the alloy of the invention, the coating decomposition is prevented by the increased edge field strengths.
