Embodiment 1

[0031] The composition of an aluminum alloy strip for a computer bracket and a manufacturing method thereof is calculated as: Si 0.05%, Fe 0.05%, Cu 0.03%, Mn 0.025%, Mg 3.0%, Cr 0.03%, Zn 0.01%, Ti 0.012%, the balance is Al and inevitable impurities.

[0032] The preparation method of the aluminum alloy strip for the computer bracket is as follows:

[0033] 1) Add aluminum ingots, aluminum master alloy ingots, magnesium ingots and manganese agent into the smelting furnace in proportion, and after melting, refining, slag removal, and stirring at 730 ° C, the stirring speed is 80 r / min, and the formed aluminum The liquid was placed in a standing furnace for 2.0 h;

[0034] 2) Add a grain refiner to the molten aluminum at 700°C, the refiner is Al-5Ti-0.2B, and the addition amount is 60~120ppm. After refining by argon gas, the refined aluminum liquid is cast into aluminum alloy flat ingot by semi-continuous casting method, and the thickness of the ingot is 400mm;

[0035] 3) A...

Abstract

The invention discloses an aluminum alloy strip material for a computer support, and a preparation method thereof. The aluminum alloy strip material for the computer support comprises the following components in percentage by mass: 0.01%-0.10% of Si, 0.03%-0.08% of Fe, 0.01%-0.10% of Cu, 0.02%-0.05% of Mn, 2.4%-3.4% of Mg, 0.01%-0.10% of Cr, 0.01%-0.02% of Zn, 0.01%-0.03% of Ti, and the balance Aland inevitable impurities, wherein the content proportion of FeMnAl6 in an intermetallic compound is not greater than 0.01%. According to the aluminum alloy strip material for the computer support, and the preparation method thereof, by controlling the chemical components of the alloy and optimizing the production parameters of casting and hot-rolling processes, the preparation method of the aluminum alloy strip material for the computer support has the advantages of being high in anodic oxidation quality, level in shape, high in forming performance, and the like, and breaks the monopoly of foreign technologies in the aspect.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metals, and in particular relates to an aluminum alloy strip for a computer bracket and a preparation method thereof. Background technique [0002] At present, computer brackets mainly use stainless steel, plastics and other materials, and stainless steel has a large proportion. With the lightweight process of 3C electronic products, the application of stainless steel materials has gradually declined, and its metallic luster is poor. Although the specific gravity of plastic material is small, it is easily damaged by foreign objects, has low strength, and has poor fire resistance and heat resistance. It is easy to deform during use, thus affecting the use. The aluminum alloy has the advantages of excellent thermal conductivity, medium strength, low density, etc., and aluminum is the metal with the largest content in the earth's crust, which provides the possibility for the development of alumin...
