Abstract

The invention discloses Al-Fe-Cu-Mg aluminum alloy and an electric wire made of the same. The aluminum alloy comprises the components of 0.2-0.4wt% of Fe, 0.3-0.5wt% of Cu and Mg and the allowance of Al and impurities. The specific resistance of the aluminum alloy is not larger than 0.02800 omega*mm<2> / m, the breaking elongation is not lower than 10%, and the average creep speed within 1-100 hours is 5 * 10-2(% / h) or lower under the condition of the temperature of 120 DEG C and the pressure stress of 120 MPa. Stress concentration cannot happen during a cold-drawing micro-pulling machining process so that an aluminum alloy rod cannot be broken, and after wire drawing, the diameter of an aluminum alloy conductor single wire can reach 0.3mm.

Description

technical field [0001] The invention relates to the field of electric wires and cables, in particular to an Al-Fe-Cu-Mg aluminum alloy and an electric wire prepared therefrom. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and is 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, and at the same time the development of the power industry has expanded the application fields of aluminum alloys. [0003] A power cable is a resource used to transmit and distribute electrical energy, and its basic structure consists of four parts: a core, an insulating layer, a shield...
