Embodiment 1

[0042]An aluminum alloy for automotive wires, the components and weight percentages of each component are as follows (total weight: 1T):

[0043]

[0044]

[0045] In the above-mentioned aluminum alloy materials, it is preferable to add a certain amount of Ni, and the addition of Ni can form AlNi in the alloy. 3 and other metal compounds, which are distributed in the grain boundary of the matrix in the form of a dispersed phase, have multiple functions of refining grains, filling the grain boundaries of the matrix, and forming metal compounds near aluminum potential, which obviously weakens the surface tension of the melt and reduces the viscosity of the melt. Significantly improves the melt fluidity and the mechanical properties of the alloy. 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 s...

[0052] An aluminum alloy for automotive wires, the components and weight percentages of each component are as follows (total weight: 1T):

[0053]

[0054] 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.

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

[0056] 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,

Abstract

The invention discloses an Al-Fe-Cu-Mg-Ni aluminum alloy for an automobile wire and a preparation method thereof as well as a prepared wiring harness. The Al-Fe-Cu-Mg-Ni aluminum alloy for the automobile wire comprises following components: Fe with the content of 0.2-1.4wt%, Cu+Mg with the content of 0.01-0.5wt%, Ni with the content of 0.001-0.2wt% and the balance of Al and unavoidable impurities. Fe element is added so that the mechanical strength and the tensile performance of the alloy can be improved; Fe can also obviously improve the high-temperature creep resistance and improve the anti-fatigue performance of the alloy; the Cu+Mg are added so as to improve the strength and the high-temperature creep resistance of the alloy and improve the anti-fatigue performance; the Ni is added so that metal compounds including AlNi3 and the like can be formed in the alloy and are distributed in a base crystal boundary in a dispersed phase manner; the alloy has a plurality of functions including thinning crystal grains, filling the base crystal boundary and forming a near aluminum potential metal compound; the surface tension of a melt is obviously weakened and the viscosity of the melt is reduced; the melt fluidity and the mechanical property of the alloy are obviously improved.

Description

technical field [0001] The invention relates to a wire harness that can be used as a storage battery cable in a mobile carrier, a wire harness or a cable for an engine, and belongs to the field of aluminum alloys. Background technique [0002] At present, the automobile industry is developing rapidly in the world. The automobile industry has not only become the pillar industry of developed countries such as the United States and Japan, but also some developing countries including China. As one of the important supporting products of automobiles, the automobile line, no matter It has a good market prospect in terms of scale output and variety demand. [0003] At the same time, automobiles are developing in the direction of miniaturization and light weight, the control circuits of various electronic devices are increasing, and the wiring positions in motor vehicles are increasing. Therefore, in order to reduce weight, attempts have been made to use aluminum electric wires who...
