Abstract

The invention discloses a 6-series aluminum alloy and a processing method thereof. The 6-series aluminum alloy includes: magnesium (Mg): 0.6-1.0 wt%; silicon (Mg): 0.4-0.8 wt%; manganese (Mn): ≤0.04 wt%; Titanium (Ti): ≤0.04 wt%; Iron (Fe): ≤0.10 wt%; Copper (Cu): ≤0.05 wt%; Chromium (Cr): ≤0.01 wt%; ) and unavoidable impurities. The invention optimizes the components of the 6 series aluminum alloy and controls the processing technology, so that the size and distribution of the intermetallic compounds are better controlled, and finally the material has a better anodic oxidation effect.

Description

technical field [0001] The invention relates to the field of nonferrous metal processing, in particular to a 6-series aluminum alloy and a processing method thereof. Background technique [0002] 6xxx aluminum alloys (6-series aluminum alloys) are widely used in the manufacture of appearance parts of electronic products that require high anodizing effects due to their better anodizing effects (such as white and bright colors). Generally, the appearance parts of electronic products will be sandblasted during the pre-treatment process of anodizing. The purpose of sandblasting is to cover the structural defects of the material (such as "grain lines", that is, thin strips along the direction of processing deformation). However, if the tissue defects are obvious and coarse, sandblasting cannot cover up the tissue defects. The main reason for the generation of material grain is that the size and distribution of intermetallic compounds in the material are not effectively controll...
