ALUMINUM ALLOY MATERIAL, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/103787
Kind Code:
A1
Abstract:
The present invention provides an aluminum alloy material, a preparation method therefor, and an application thereof. According to the aluminum alloy material of the present invention, by means of alloy component design, the material can have good surface treatment performance while the yield strength is greater than 450 MPa. The aluminum alloy material of the present invention is small in stress deformation after being machined by a numerical control lathe. Taking a finished product of a middle frame of a bar phone having the length of 170 mm, the width of 80 mm, and the thickness of 7 mm as an example, the flatness can be controlled within 0.15. According to the aluminum alloy material of the present invention, the aluminum alloy is mechanically polished without trailing lines, and an oxidation film is transparent, such that high brightness can be achieved, and the anodic oxidation effect is good. The present invention further provides a preparation method for the aluminum alloy material and an application thereof in preparation of a 3C product housing.
