[0035] In the above-mentioned aluminum alloy materials, it is preferable to add a certain amount of Sb. After adding Sb to the aluminum alloy, it can form stable multi-component compounds with aluminum, iron, magnesium, and copper in the alloy. The density of these compounds is similar to that of the alloy liquid. When the alloy is solidified, they are first precipitated, forming a network framework, suspended in the alloy liquid, and hindering the floating of the aluminum-rich phase and the falling of the iron-rich, magnesium, and copper phases, thereby inhibiting the specific gravity segregation of the alloy that is e...

[0045] 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.

[0046] The method for preparing an aluminum alloy wire core by using the above-mentioned aluminum alloy material, the specific steps are as follows:

[0047] 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,

[0054] 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...

Abstract

The invention discloses an Al-Fe-Cu-Mg-Sb aluminum alloy for an automotive wire, a manufacturing method of the aluminum alloy, and a wiring harness made of the aluminum alloy. The Al-Fe-Cu-Mg-Sb aluminum alloy for the automotive wire comprises the following ingredients in percentage by weight: 0.2-1.4wt% of Fe, 0.01-0.5wt% of Cu and Mg, 0.001-0.2wt% of Sb, and the balance of Al and inevitable impurities. The mechanical strength and the tensile properties of the alloy can be improved by adding an Fe element; the high temperature creep resistance also can be obviously improved by Fe; the anti-fatigue performance of the alloy is improved; the strength and the high-temperature creep properties of the alloy can be improved by adding Cu and Mg; the anti-fatigue performance can be improved; the yield limit of the alloy can be improved by adding Sb; meanwhile, the alloy has superplasticity, so as to be drawn into a very thin alloy wire.

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...
