[0043]In the above-mentioned aluminum alloy materials, it is preferable to add a certain amount of Zn. The addition of Zn will slightly reduce the electrical conductivity of the aluminum alloy, but can effectively improve the strength to a certain extent, and at the same time improve the creep rate of the conductor. It is preferable to add a certain amount of Cu, which has a certain solid solution strengthening effect, and the CuAl precipitated by aging 2 It has obvious aging strengthening effect, and the copper content in the alloy is most suitable at 0.01%-0.3%. If it exceeds this range, its aging strengthening effec...

[0053] 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.
[0054] The method for preparing an aluminum alloy wire core by using the above-mentioned aluminum alloy material, the specific steps are as follows:
[0055] 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 temp...

[0062] In the above-mentioned aluminum alloy materials, it is preferable to add a certain amount of RE elements, wherein Ce and La account for 50% 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 Increase the supercooling of the composition, refine the grain, reduce the secondary grain distance, reduce the gas and inclusions in the alloy, and make the inclusion phase tend to be spheroidized. It can also reduce the surface tension of the melt,...
