Abstract

The invention belongs to the technical field of aluminum strip calendering manufacturing, and discloses a low-earing and low-hardness capacitor shell and a preparation method thereof. The low-earing and low-hardness capacitor shell comprises the following components in percentage by mass: 0.1% of Si, 0.18-0.28% of Fe, not greater than 0.03% of Cu, not greater than 0.01% of Mn, not greater than 0.03% of Zn, not greater than 0.03% of Ti, and the balance Al. The process flow comprises such steps as smelting, cast rolling, rough rolling, edge cutting, finish rolling and finished product annealing;and the prepared capacitor shell is 75-85Mpa in tensile strength, can reach the elongation above 30%, is excellent in machining performance, low in strength, excellent in plasticity, high in elongation and low in earing rate, and greatly improves the machining efficiency.
