Description

technical field [0001] The invention relates to an iron-aluminum alloy wire and a manufacturing method thereof, in particular to an iron-aluminum alloy wire containing copper and a manufacturing method thereof. Background technique [0002] With the continuous development of the communication industry, the demand and usage of cables are increasing, and the performance and service life of the cables themselves determine the quality and stability of communications. In the early 1980s, in China, the use of aluminum conductor cables surged, and even small-sized construction cables also used aluminum conductors. Due to the low cost and wide source of aluminum, aluminum core cables made of pure aluminum are widely used. Due to the relatively poor creep and connection properties of pure aluminum conductors, oxidation and loosening are prone to occur at the joints, causing accidents such as fires and power outages. According to statistics, the failure rate of pure aluminum cables ...
