Aluminum alloy rod for shielding

Abstract

The invention discloses an aluminum alloy rod for shielding. The aluminum alloy rod for shielding is composed of the following components in parts by weight: 100 parts of aluminum, 0.04-0.06 parts of silicon, 1-1.3 parts of iron, 0.18-0.28 parts of copper, rare earth 0.08-0.1 parts of elements, 0.015-0.03 parts of boron, 0.01-0.02 parts of titanium, and 0.01-0.02 parts of beryllium; the rare earth elements are composed of lanthanum, cerium and scandium, and the ratio of lanthanum, cerium and scandium to 14:6:1 The rare earth elements are formed by mixing in proportions by weight. The metal structure of the aluminum alloy rod for shielding of the present invention is significantly improved, and the tensile strength and elongation are greatly improved after production tests and subsequent wire drawing, and the macroscopic grain size can reach 6-8 levels.

Description

technical field [0001] The invention relates to an aluminum alloy rod, in particular to an aluminum alloy rod for shielding. Background technique [0002] Aluminum alloy is one of the most widely used non-ferrous metal materials in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of science and technology and industrial economy, the demand for aluminum alloys is increasing, and the research on aluminum alloys is also in-depth. The wide application of aluminum alloys has promoted the development of aluminum alloys in the power industry, while the development of the power industry has promoted the application of aluminum alloys. [0003] As the aluminum alloy rods used for shielding aluminum alloy lines, the commonly used aluminum alloy rods should be drawn to 0.10-0.12mm. At present, in the cable field of the machining industry, after the traditional aluminum rod or...

AI Technical Summary

Problems solved by technology

At present, in the cable field of the machining industry, after the traditional aluminum rod or aluminum alloy rod is manufactured, due to the limitation of the structure of the material, the performance of the material during processing is affected, and its tensile strength and elongation are low. , the tensile strength is only 180Mpa, and the elongation is only 10%. In the subsequent drawing process, it will cause early broken wires or unqualified strength, which not only causes waste of raw materials, but also increases production costs.
