[0035]In the above-mentioned aluminum alloy materials, it is preferable to add a certain amount of Be. Be forms α and β dispersive high-temperature strengthening phases in the alloy, which can prevent the oxidation, burning loss and gas absorption of alloy elements, and improve the smelting quality of the alloy and the hardness of the surface oxide film. Density. Be can also change the impurity iron from acicular to agglomerated, which can prevent the recoil of sand castings and models during pouring. Due to Be's high affinity for oxygen and nitrogen, it is highly effective at degassing the melt, resulting in high-qua...

[0046] 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.

[0047] The method for preparing an aluminum alloy wire core by using the above-mentioned aluminum alloy material, the specific steps are as follows:

[0048] 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...

[0056] 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, 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 the service life of the...

Abstract

The invention discloses an Al-Fe-Cu-Mg-Be alumium alloy for an automobile wire and a preparation method thereof, and an automobile wiring harness prepared by the preparation method. The Al-Fe-Cu-Mg-Be alumium alloy for the automobile wire comprises the following components: 0.2-1.4wt% of Fe, 0.01-0.5wt% of Cu+Mg, 0.001-0.2wt% of Be, and the balance of Al and inevitable impurities. According to the invention, Fe element is added so that the mechanical strength and the tensile property of the alloy can be improved; Fe is also capable of obviously improving the high-temperature creep resistance and the fatigue resistance of the alloy; the addition of Cu+Mg is capable of improving the strength and the high-temperature creep property and the fatigue resistance of the alloy; Be is capable of improving the smelting quality of the alloy and the compactness of the surface oxide film, so that good-quality castings good in surface smoothness, high in strength and improved in ductility can be obtained; Be is also capable of improving the fluidity of the alloy so that the fluidity of the melt is improved, and can further improve the tensile strength and the limit of yielding of the alloy.

Description
