Embodiment 1

[0037] The ingot is extruded, quenched, stretched, sampled from the head and tail, finely straightened, aged, cut into finished products, inspected and packed into the warehouse in order to obtain aluminum alloy extruded profiles;

[0038] The temperature of the ingot is 430°C (extrusion temperature);

[0039] The cylinder temperature during the extrusion process is 435°C, the mold temperature is 430°C, the mold heating and holding time is 3 hours, and the extrusion speed is 0.3-0.36m / min;

[0040] The solution holding temperature of the quenching is 530°C, and the solution holding time is 20min;

[0041] The elongation rate of described stretching is 3%;

[0042] The aging temperature is 191° C. and the time is 18 hours.

[0043] The surface of the extruded profile was observed, and there was no crack on the surface of the extruded profile.

Embodiment 2～4

[0045] Aluminum alloy extruded profiles were prepared according to the method of Example 1. The difference from Example 1 was that the extrusion speeds were 0.5-0.56 m / min, 0.76-0.82 m / min, and 0.98-1.02 m / min.

[0046] The surface of the extruded profile was observed, and the surface of the extruded profile was not cracked.

Embodiment 5

[0048] The aluminum alloy extruded profile was prepared according to the method of Example 1, the difference from Example 1 was that the extrusion temperature was 450°C.

[0049] The surface of the extruded profile was observed, and there was no crack on the surface of the extruded profile.
