Description

technical field [0001] The invention relates to the field of cable manufacturing, in particular to an aluminum alloy wire with good mechanical properties and electrical conductivity and a preparation method. Background technique [0002] Conventionally, as electrical wiring bodies for moving objects such as automobiles, trains, and airplanes, terminals made of copper or copper alloys (such as brass) are attached to electric wires containing copper or copper alloy conductors called wire harnesses. (connector, connector) and get the components. In recent years, in the course of reducing the weight of mobile bodies, studies have been conducted to use aluminum or an aluminum alloy that is lighter than copper or a copper alloy as a conductor of an electrical wiring body. [0003] Pure aluminum (1000 series) is mostly used for power transmission lines, and its tensile strength is low, so it is not strong enough for wiring harnesses. Contents of the invention [0004] Aiming at...
