Problems solved by technology

[0002] For aluminum alloy conductors, there are two important quality indicators: one is resistivity, which directly affects the conductivity of aluminum alloy conductors. The resistivity is mainly determined by the chemical composition of raw materials, especially in In aluminum alloy, if copper, iron, zinc, magnesium and other impurity elements are added, the conductive effect of wire and cable will be deteriorated; the second is mechanical properties, when ordinary electrical aluminum is used as a conductor, the elongation, flexibility and The creep resistance is poor, and the safety and stability of use are low

Abstract

The invention discloses a special-shaped oxidation-resistant high-conductivity aluminum alloy carbon fiber lead wire which is manufactured by twisting and compressing special-shaped aluminum alloy monofilaments and composite carbon fibers, wherein the special-shaped aluminum alloy monofilaments consist of components by mass percent: 0.10-0.80% of iron, 0.15-0.30% of copper, 0.05-0.10% of silicon, 0.05-0.10% of zinc, 0.01-0.05% of magnesium, 0.02-0.12% of rare earth elements, 98-99% of aluminum, and the balance of impurities. The aluminum alloy obtained in the invention is a novel Al-Cu-Fe alloy material with high tensile strength, higher elongation and easiness in drawing and machining, and the finally manufactured lead wire is low in resistance rate and high in elongation.
