Abstract

The invention discloses an aluminum alloy material, an aluminum alloy product and a preparation method of the aluminum alloy product, wherein the aluminum alloy material comprises, by mass, 4.5-8% ofzinc, 1-2% of magnesium, 0-1.0% of copper, less than or equal to 0.05% of silicon, less than or equal to 0.2% of iron, less than or equal to 0.02% of chromium, less than or equal to 0.025% of titanium, less than or equal to 0.1% of zirconium, less than or equal to 0.05% of other single impurity elements, less than or equal to 0.2% of rare earth element, and the balance of aluminum. According to the present invention, the anode oxidation film can be formed on the surface after the aluminum alloy material is subjected to anode oxidation so as to from the aluminum alloy product, wherein the aluminum alloy product has excellent wear resistance and good durability.

Description

technical field [0001] The invention relates to the technical field of material preparation, and more specifically, to an aluminum alloy material, an aluminum alloy product and a preparation method thereof. Background technique [0002] Aluminum alloys are made by adding other alloying elements to pure aluminum. Aluminum alloy has the advantages of low density, excellent corrosion resistance, good plasticity and processing performance, strong electrical and thermal conductivity, low temperature brittleness resistance, good surface treatment performance, non-magnetic, acid resistance, and excellent radiation resistance. [0003] Since aluminum alloy can obtain the ideal surface effect through artificial anodizing, it can be used as the shell of decorative materials, which makes the application of aluminum alloy in the electronics industry, especially in the fields of smart phones and smart wearables, more and more common. At present, aluminum alloys used as decorative materi...
