Abstract

The invention relates to an aluminum-copper-magnesium alloy wire rod and a manufacturing technique of the aluminum-copper-magnesium alloy wire rod. The aluminum-copper-magnesium alloy wire rod is formed by the following raw materials in percentage by weight: 0.2-2.5% of copper, 0.2-2.8% of magnesium, 0.1-0.6% of silicon, 0.2-0.7% of iron, 0.03-0.5% of boron, 0.03% of manganese, 0.03% of zinc, 0.03% of chrome, 0.01% of titanium, and 96%-98% of aluminum. The manufacturing technique comprises the following steps: (1), smelting of aluminum alloy, (2), online treatment of aluminum alloy, (3), casting of aluminum alloy, (4), rolling of aluminum alloy wire rod, and (5), carrying out online aging treatment on the rolled aluminum alloy wire rod to obtain the wire rod, wherein the drawing out temperature is not higher than 60 DEG C. The aluminum-copper-magnesium alloy wire rod meets the performance requirements on the raw material aluminum alloy wire rod in copper clad aluminum alloy in the cable industry field, in particular the requirements on the performances in the aspects of tensile strength, percentage elongation and compressive creep, and the like.

Description

technical field [0001] The invention relates to an aluminum alloy material, in particular to an aluminum-copper-magnesium alloy wire rod and a manufacturing process. Background technique [0002] For a long time, in the cable industry, copper has always been the dominant conductor due to its superior electrical conductivity and heat transfer performance. However, due to the shortage of copper resources and the rapid growth of demand, the price of copper has risen sharply, making the consumer market of copper have been looking for A suitable substitute, aluminum and aluminum alloys have similar functions to copper in terms of electrical conductivity and heat transfer, which determines that aluminum and aluminum alloys are the main substitute materials for copper. [0003] The electrical and mechanical properties of copper-clad aluminum alloy wire are between copper and aluminum alloy. It combines the excellent electrical conductivity of copper and the advantages of light weig...
