  • Patent number: 11566312
    Abstract: A manufacturing process of a high-strength aluminum alloy wire/strip includes the following steps: A. subjecting an alloy to smelting and spray forming to obtain a high-strength Al—Zn—Mg—Cu aluminum alloy blank; B. subjecting the blank to semi-solid upset forging to form an ingot; C. subjecting the ingot to hot extrusion and then to vacuum annealing to form a coiled material; D. subjecting the coiled material to hot continuous rolling to obtain a wire blank; and E. subjecting the wire blank to solution heat treatment, multiple stretching treatments, annealing, and multiple continuous stretching treatments to obtain the high-strength aluminum alloy wire/strip. The high-strength aluminum alloy wire/strip has the characteristics of fine and compact grains, uniform structure, clear grain boundaries, no precipitates, and no layered structure affecting the stretching performance.
