Problems solved by technology

However, the strength, fatigue resistance and toughness of pure aluminum are lower than that of copper, so pure aluminum cannot be used alone as a wire, especially in the field where the cross-section of the wire is required to be small

Description

technical field [0001] The invention relates to the technical field of alloy wire manufacture, in particular to an aluminum alloy wire material and a production process thereof. Background technique [0002] In recent years, the technology of using aluminum or an aluminum alloy which is lighter than copper or copper alloy as a conductor of an electrical wiring body has been rapidly developed in the lightening process of moving objects. [0003] As we all know, the specific gravity of aluminum is about 1 / 3 of that of copper, and the conductivity of aluminum is about 2 / 3 of that of copper (when pure copper is 100% IACS, pure aluminum is about 66% IACS). Therefore, in order for the same current to flow through the pure aluminum conductor wire as that of the pure copper conductor wire, the cross-sectional area of ​​the pure aluminum conductor wire needs to be about 1.5 times that of the pure copper conductor wire. Even so, aluminum is only about half of copper in terms of weight...
