The application of pitting in the measuring cubic texture content of Al foil for Aluminum electrolytic capacitor and electrochemical characteristics of pitting were introduced. Formation and feature of cubic texture of Al foil were also discussed. The elastic modulus of crystal plane in polycrystalline materials as well as the atomic density of crystal plane and crystal orientation were simulated and calculated. The inherent relation between material grain orientation and pitting orientation are explored and further proved by experiments.
