- the manufacturing method of the second invention realizes the metal structure and tensile strength of the aluminum alloy plate defined in the first invention, thereby producing an aluminum alloy plate that exhibits excellent skin roughness, formability and high strength. can do.
- Mg increases the strength by dissolving in the matrix. It also increases work curability, thereby contributing to improved moldability. If the Mg content is less than 2.0 mass%, the strength decreases. 3. If it exceeds 3 mass%, the yield strength becomes too high and the shape freezing property decreases.

If the Mn content is less than 0.1 mass%, the effect is not sufficient. If it exceeds 0.5 mass%, the average grain size exceeds 1 zm during the fabrication of the alloy, and A 1 — (F e ⁇ M n) 1 Si-based crystallized product is formed and the formability deteriorates.

- the Ti content exceeds 0.110 mass%, a relatively coarse A 1 Ti intermetallic compound is crystallized during fabrication, thus lowering the formability. Therefore, the preferable Ti content is 0.10 mass% or less. A more preferable Ti content is not more than 0.05 mass%.
- the average equivalent circle diameter of intermetallic compounds is 1 / im or less, and the area ratio of intermetallic compounds is 1.2% or more.

- the temperature of the final annealing in the continuous annealing furnace is limited to 400 to 520 ° C. If the temperature is less than 400 ° C, the energy required for recrystallization is insufficient, so that a fine recrystallized structure cannot be obtained. When the holding temperature exceeds 5220 ° C, the growth of recrystallized grains becomes prominent, and the average grain size of recrystallized grains exceeds 10 x ⁇ m, and the formability and rough surface properties deteriorate.
