[0041] In the above-mentioned aluminum alloy materials, it is preferable to add a certain amount of V. The addition of V forms a VAl11 refractory compound in the aluminum alloy, which plays a role in refining the grains during the melting and casting process, and also has the effect of refining the recrystallization structure and increasing the recrystallization temperature. . Generally, cast aluminum alloys have thermal expansion and contraction, so in some high-temperature conditions, high-temperature density may increase. In the case of adding V to the cast aluminum alloy liquid, the method of co-melting and casting can...

[0048] An aluminum alloy for automotive wires, the components and weight percentages of each component are as follows (total weight: 1T):

[0049]

[0050] Among the above-mentioned aluminum alloy materials, the content of Si was compared. An appropriate amount of Si can increase the recrystallization temperature and refine the grains, while exceeding a certain content will reduce its electrical conductivity. In the process of implementation, it was found that the Si content Excessive samples are prone to breakage during the wire drawing process.

[0051] The method for preparing an aluminum alloy wire core by using the above-mentioned aluminum alloy material, the specific steps are as follows:

[0052] a. Melting and casting: add aluminum alloy components according to the above ratio, melt at 730°C, cast ingots at 670°C, and then roll into alloy rods after solution treatment and aging treatment. The aging treatment here is preferably at 140°C or at higher temperatures,

[0058]

[0059] In the above-mentioned aluminum alloy materials, it is preferable to add a certain amount of RE elements, wherein Ce and La account for more than 52% of the total RE content, and rare earths can significantly improve the electrical properties of the alloy. In the present invention, rare earths are added to the aluminum alloy to make the aluminum alloy melt and cast When increasing the supercooling of the composition, the crystal grains are refined, the secondary grain distance is reduced, the gas and inclusions in the alloy are reduced, and the inclusion phase tends to be spheroidized. It can also reduce the surface tension of the melt, increase the fluidity, and is conducive to casting into ingots. It has a significant impact on the process performance, and can also improve the fatigue resistance of the alloy and prolong...
