Description

technical field [0001] The invention relates to the technical field of aluminum profiles, in particular to an aluminum alloy profile and a manufacturing method thereof. Background technique [0002] Aluminum alloy has low density, high strength, excellent electrical and thermal conductivity, good plasticity, no low temperature brittleness, and easy processing, so it is widely used. However, the self-corrosion potential of aluminum alloy is relatively negative, which makes aluminum and its alloys prone to corrosion. In order to improve the comprehensive performance of aluminum alloy, surface treatment technology is often used to treat aluminum alloy. The anodic oxidation reaction of aluminum alloy is the electrochemical oxidation reaction of aluminum alloy through electric current under external voltage, forming a layer of aluminum oxide film on the surface of aluminum alloy to improve the hardness and corrosion resistance of aluminum alloy. However, the microhardness of al...
