High-power-density electron beam with single pulse was performed on the LD11R aluminum alloy. Variation of penetration depth and cavity width with focus position and duration time was studied by using the "rapid fixing" method. The influence of focus position on deep penetration was investigated as well. An electron beam deep penetration mechanism is proposed. The results indicate that the electron fusion range rate was the main factor of the deep penetration.
