Abstract:The copper wires are widely used in integrated circuit bonding wire, audio and video transmission cable, active wiring harness of medical devices, and various electronic components. It is the key conductor material to ensure the stable transmission of system current and signal. Based on the preparation process of copper wire, this paper reviews the process characteristics of hot mold horizontal continuous casting and cold mold vertical continuous casting, and their relationship with the directional solidification structure of as-cast copper rod. The effects of process parameters such as continuous drawing, heat treatment, and surface coating on the characteristics of grain size, precipitated phase, surface coating, and bonding were discussed. Finally, the development trend of application field and equipment technology of copper based wire under the background of “new infrastructure construction” was prospected.
Key words: copper based materials; wire; hot mould horizontal continuous casting; cold mould vertical continuous casting; continuous drawing; surface coating
