Abstract

The invention is suitable for the field of material processing, and provides an aluminum alloy and a preparation method thereof. The aluminum alloy comprises the following components in percentage bymass: 0.62-0.78% of silicon, 0.56-0.70% of magnesium, 0.15-0.20% of copper, 0.25-0.38% of manganese, 0.10-0.18% of chromium, 0.03-0.08% of vanadium, iron not more than 0.20% and more than 0, titaniumnot more than 0.03% and more than 0, and the balance of aluminum. In the aluminum alloy, through limiting of the contents of silicon, magnesium and copper fed elements, the product strength is improved when the extrusion performance of the aluminum alloy is not reduced; and meanwhile, through feeding of such elements as manganese, chromium and vanadium and cooperation with subsequent process treatment, dispersion separation mass points can be generated to achieve an effect of inhibiting recrystallization in the extrusion process, that is, the product strength and ductility are further improved, and prepared products achieve higher strength, ductility, stress corrosion resistance and extrusion performance.

Description

technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to an aluminum alloy and a preparation method thereof. Background technique [0002] Aluminum alloy is a very common material that is widely used in various industries. In order to meet the needs of different industries, it is usually necessary to add a certain amount of alloying elements such as silicon, magnesium, titanium, copper, chromium, etc. to pure aluminum, and adding different types of alloying elements or adding different dosages of alloying elements will affect the final Properties of the prepared aluminum alloys. The 6-series aluminum alloy is an aluminum alloy with magnesium and silicon as the main additive elements. It is a heat-treated alloy that can be strengthened. It has good corrosion resistance, oxidation resistance and extrudability. It is widely used, from various From hardware parts to aluminum alloy doors and windows to airplanes an...
