Description

technical field [0001] The invention relates to the technical field of electric power fittings, in particular to an aluminum alloy material used for manufacturing power cable connecting fittings and a preparation method thereof. Background technique [0002] Power fittings are metal accessories that connect and combine various devices in the power system to transmit mechanical loads, electrical loads and some kind of protection. Most of the fittings need to withstand large tension during operation, and some of them also need to ensure good electrical contact, which is related to the safety of wires or towers. Even if one is damaged, it may cause line failure. Therefore, the quality of fittings, Correct use and installation have a certain impact on the safe power transmission of the line. [0003] The material is a crucial aspect in the manufacture of power fittings, and the existing power fittings materials have general performance in terms of toughness and wear resistance,...
