Manufacturing method of high-strength alloy cold-drawn wire for aircraft fastener

The invention relates to a manufacturing method of a high-strength alloy cold-drawn wire for an aircraft fastener. The manufacturing method comprises the following steps: taking return steel, chromium metal, a nickel plate, pure iron, manganese metal, molybdenum metal, pure titanium, aluminum metal, ferroboron and nickel-magnesium alloy as raw materials, and performing a smelting process through a vacuum induction furnace and a consumable electrode vacuum furnace to obtain a steel ingot; carrying out forging hot working and rolling hot working on the steel ingot to obtain a wire rod blank; and after the wire rod blank is subjected to solid solution, surface treatment and cold drawing machining, the high-strength alloy cold-drawn wire for the aircraft fastener is obtained. When the vacuum induction furnace and the consumable electrode furnace are used for smelting, the return steel is used, so that the addition of metal chromium, pure iron and nickel plates is greatly reduced, and the production cost is reduce
