Embodiment 1
[0028] After the aluminum alloy ingot is homogenized in a circulating air resistance furnace at 470°C×5h+540°C×15h, it is cut and face milled, hot rolled, intermittently annealed and finally cold rolled into a thin plate with a thickness of 1mm. After the sheet was quenched by solution treatment at 560°C×30min in an air circulation resistance furnace, it was immediately treated in an oil bath furnace at 65°C×5h, and then parked at room temperature for 1 month, 2 months, 3 months and Hardness test and tensile test were carried out after 4 months. The simulated paint baking is carried out in an oil bath furnace at a temperature of 180°C×30min. After the paint is baked, the hardness test and tensile test are carried out.
Embodiment 2
[0030] After the aluminum alloy ingot is homogenized in a circulating air resistance furnace at 470°C×5h+540°C×15h, it is cut and face milled, hot rolled, intermittently annealed and finally cold rolled into a thin plate with a thickness of 1mm. After the thin plate was quenched by solution treatment at 560°C×30min in an air circulation resistance furnace, it was immediately treated in an oil bath furnace at 65°C×15h, and then parked at room temperature for 1 month, 2 months, 3 months and Hardness test and tensile test were carried out after 4 months. The simulated paint baking is carried out in an oil bath furnace at a temperature of 180°C×30min. After the paint is baked, the hardness test and tensile test are carried out.
Embodiment 3
[0032] After the aluminum alloy ingot is homogenized in a circulating air resistance furnace at 470°C×5h+540°C×15h, it is cut and face milled, hot rolled, intermittently annealed and finally cold rolled into a thin plate with a thickness of 1mm. After the sheet was quenched by solution treatment at 560°C×30min in an air circulation resistance furnace, it was immediately treated in an oil bath furnace at 65°C×25h, and then parked at room temperature for 1 month, 2 months, 3 months and Hardness test and tensile test were carried out after 4 months. The simulated paint baking is carried out in an oil bath furnace at a temperature of 180°C×30min. After the paint is baked, the hardness test and tensile test are carried out.
