Description

technical field [0001] The invention relates to the field of wire and cable manufacturing, in particular to a method for preparing an aluminum alloy cable for automobiles. Background technique [0002] Because copper is expensive and relatively heavy, the conductive core of insulated wires and cables is currently made of aluminum instead of copper, and most of them are made of hard aluminum wire. With the widening of the use of aluminum alloy materials, according to the use of different regions, It can be used in coal mine wires, communication wires, high-speed rail wires, automobile wires, and electromagnetic wires, etc. According to different usage scenarios, different performances are required to meet the needs of use. [0003] In automotive wires, the aluminum alloy wire used must not only ensure that the aluminum alloy wire has good stretchability, but also has good flexibility, which is not easy to achieve with ordinary aluminum alloys, and has good fatigue resistance ...
