Problems solved by technology

Although copper wires and cables still account for the majority of the market share, this cannot conceal the rising trend of the market share of aluminum alloy cables
[0004] However, aluminum alloy cables still have the disadvantages of high resistivity, low carrying capacity, and high heating temperature.

Abstract

The invention provides an aluminum alloy cable core, comprising the following components by weight percentage: Mg 0.02-0.08%, modified graphene 0.2-0.4%, and the balance of Al and impurities. The modified graphene is mainly prepared from nanometer TiO2, Fe powder, B powder, copper powder and graphene powder. The aluminum alloy cable core not only has low electrical 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 aluminum alloy cable core. 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 a time when the in...
