Abstract

The invention discloses an Al-Fe-Cu-Mg-Ti aluminum alloy for an automobile wire, a preparation method thereof, and an automobile wiring harness prepared by the Al-Fe-Cu-Mg-Ti aluminum alloy. The Al-Fe-Cu-Mg-Ti aluminum alloy for the automobile wire comprises following components in percentage by weight: 0.2-1.4% of Fe, 0.01-0.5% of Cu and Mg, 0.001-0.2% of Ti, and the balance of Al and inevitable impurities. The mechanical strength and tensile performance of the alloy can be improved by adding the Fe element, the anti-creepage property and fatigue resistance property can be obviously enhanced through the Fe, the added Ti can play a role on the micronization material of ingots in casting, the processing tensile property of the alloy can be enhanced, and the anti-creepage property can be improved, especially the stability with a connecting terminal can be enhanced.

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...
