Aluminum alloy wire harness for light automobile and preparation method thereof

Abstract

The invention discloses an aluminum alloy wire harness for a light automobile. The aluminum alloy wire harness for the light automobile comprises a conductor wire core and an outer layer insulating layer, wherein the conductor wire core comprises the following components of 0.2wt%-0.4wt% of V, 0.01wt%-0.3wt% of Cu+Mg, 0.001wt%-0.01wt% of Sb, 0.01wt%-0.05wt% of Ti, 0.001wt%-0.002wt% of Ag+F, 0.001wt%-0.003wt% of Zr, 0.1wt%-0.3wt% of RE, and the balance is Al; the alloy does not contain Si and Fe; Ce and La are 50% of the total amount of the RE or more; and in a wire drawing process, the conductor wire core is firstly subject to dipping in a mixed solution of potassium fluoborate and polydimethylsiloxane, intermediate annealing in a nitrogen atmosphere containing 5% oxygen concentration is carried out, and then wire drawing is carried out. According to the aluminum alloy wire harness and the preparation method, V, Ti, Ag, F and Zr are adopted as reinforcing systems and secondary smeltingis adopted, so that the elongation at break and the tensile strength of the aluminum alloy wire harness for the light automobile are improved.
