Compared with the prior art, the high-strength aluminum alloy rivet line according to the embodiment of the invention has the advantages that a plurality of elements are alloyed, an intermediate alloy is granulated and added as particles, the technologies of high-temperature rapid aluminum smelting, electromagnetic stirring and the like are utilized comprehensively, and sectional temperature control, directional freezing, continuously casting, cold rolling, repeated thermal treatment and drawing processes are adopted, so that a rivet line with high strength, high shearing strength, excellent plasticity and toughness and superior corrosion resistance can be manufactured, the riveting weight and cost can be lowered, and the safety performance of riveting is enhanced.

Description

technical field [0001] The invention belongs to the field of metal materials, and relates to an aluminum alloy rivet wire and a preparation method thereof, in particular to a high-strength aluminum alloy rivet wire and a preparation method thereof. Background technique [0002] Rivets are riveted parts that are riveted by their own deformation or interference connection, and are widely used in construction, automobiles, ships, aircraft, machines, electrical appliances, furniture and other products. According to material classification, rivets are mainly divided into metal material rivets and non-metallic plastic rivets; while metal material rivets are mainly divided into stainless steel rivets and aluminum alloy rivets. [0003] Rivets are made of wire, and the performance of the wire determines the performance of the rivet to a large extent. How to manufacture a wire for rivets with excellent performance is very important. [0004] Rivets made of stainless steel have a low...
