Abstract

The invention relates to the technical field of mobile phone shells, specifically to a high-strength high-surface aluminum alloy for a mobile phone shell and a preparation method therefor. The aluminum alloy comprises the following chemical components in percentage by weight (wt%): 0.70%-1.4% of Si, less than or equal to 0.15% of Fe, 0.60%-1.0% of Cu, 0.50%-0.80% of Mn, 0.60%-1.20% of Mg, less than or equal to 0.015% of Ti, less than or equal to 0.05% of other singles, and the balance of aluminum. According to the aluminum alloy for the mobile phone shell, the appearance requirement and the strength requirement of the high surface of the aluminum alloy for the mobile phone shell are combined, a new aluminum alloy chemical component and a preparation process are optimally designed, the yield strength of the alloy is greatly improved while the high surface quality of the aluminum alloy for the mobile phone shell is guaranteed, and the use requirement of a mobile phone shell material is met. The aluminum alloy is anodized after CNC, the defects of material lines, so that black spots, black lines, chromatic aberration and piebald spots are avoided, and the rejection rate caused by the defects is greatly reduced; and meanwhile, the aluminum alloy is high in yield strength, and the yield strength of the aluminum alloy is not lower than 360 MPa.

Description

technical field

[0001] The invention relates to the technical field of mobile phone casings, in particular to an aluminum alloy for high-strength and high-surface mobile phone casings and a preparation method thereof. Background technique

[0002] With the popularity of smart phones and the improvement of living standards, aluminum alloys for mobile phone casings with metallic texture and high surface have been widely used. High-end smartphone casings have phased out traditional plastic, aluminum alloy die-casting, stainless steel, and titanium alloy casings, and high-surface, high-strength aluminum alloys with CNC and surface treatment are commonly used. The 6000-series aluminum alloy extruded aluminum was first used in Apple iPhone6 ​​and Apple iPhone6plus high-end smart phones. Its metal texture, bright colors and other advantages have been sought after by the mobile phone market. The 6000-series aluminum alloy has excellent extrusion deformation processing performance, ...
