Problems solved by technology

[0003] In addition, in the process of brass production, the rod blanks pulled out of the melting furnace are drawn by a giant drawing machine or a large drawing machine and then enter the subsequent process. However, internal cracks and stress cracks in the wire core often occur during the giant drawing process. , distortion, drawing fracture, uneven thickness of the pipe, scratches on the surface of the product and other defects, to a certain extent, change the structure of the wire and enlarge the defects in the slab, which is not conducive to subsequent production
[0004] At present, due to the unreasonable ratio of some alloying elements in the alloy wire, the hardness and wear resistance of the material are not high, and the impact toughness and fracture resistance of the material are not good.

Description

technical field [0001] The invention belongs to the technical field of alloy wire manufacture, and in particular relates to a wire and a preparation method thereof. Background technique [0002] Copper alloy wire has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. As electrical wiring bodies of mobile bodies such as automobiles, trains, and airplanes, or electrical wiring bodies of industrial robots, terminals made of copper or copper alloys (such as brass) ( Connectors) are called wiring harnesses. In recent years, the high-performance and high-functionality of automobiles has been rapidly developed. Along with this, the number of various electrical equipment and control equipment installed in the vehicle has increased, and the number of electrical wiring bodies used for these equipment has also increased. Propensity. With the rapid development of the automobile industry, higher requirements are placed on the wear resistance o...
