Al-Cu-Mg-Zr series aluminum alloy for cable

Abstract

The invention provides an Al-Cu-Mg-Zr series aluminum alloy for a cable. The Al-Cu-Mg-Zr series aluminum alloy comprises the following components of, by weight, 0.03-0.09% of Cu, 0.01-0.03% of Zr, 0.02-0.08% of Mg, 0.2-0.4% of modified graphene, and the balance Al and impurities. The modified graphene is mainly prepared from nano-TiO2, Fe powder, lanthanum oxide, zinc powder and graphene powder. The aluminum alloy not only has low resistivity, but also has good creep resistance.

Description

technical field

[0001] The invention belongs to the technical field of aluminum alloys, and in particular relates to an Al-Cu-Mg-Zr series aluminum alloy for cables. Background technique

[0002] At present, the cable industry is the second largest industry in China after the automobile industry, and in the world, the total output value of China's cables has surpassed that of the United States, becoming the world's largest wire and cable producer. With the continuous and rapid growth of China's economy and the continuous expansion of the power industry, data communication industry, urban rail transit industry and other industries, the demand for cables will also grow rapidly, and the wire and cable industry still has huge development potential in the future.

[0003] As we all know, my country's copper resource reserves are relatively insufficient and largely rely on imports. Therefore, it is becoming more and more important to find substitutes for copper wires and cables at...
