Abstract

The invention discloses a high-zinc-copper alloy cutting bus and a processing method thereof. The high-zinc-copper alloy cutting bus comprises determined components, components capable of being replaced with one another and inevitable impurities, wherein the determined components comprise 58.5-60.0 percentage by weight of Cu, 40-41.5 percentage by weight of Zn, 0.05-2.0 percentage by weight of Ni, 0.01-0.05 percentage by weight of Si and 0.001-0.1 percentage by weight of Fe, and the components capable of being replaced with one another is one or multiple of P or Al or Zr or Cr or Mg or a rare earth (RE) element. The high-zinc-copper alloy cutting bus processed by the method has high tensile strength, high zinc content and high softening point. Meanwhile, the processing method of the high-zinc-copper alloy cutting bus achieves the purposes of short process and high efficiency.

Description

technical field [0001] The invention relates to the field of nonferrous metal processing, in particular to a high-zinc-copper alloy cutting busbar and a processing method thereof. Background technique [0002] High-zinc-copper alloy cutting busbar material is mainly used to produce high-zinc-copper alloy electrode wire, which has high zinc content, high tensile strength, high softening point and good plastic processing performance. When the high-zinc-copper alloy electrode wire is discharged during the online cutting process, the zinc in the material will gasify, and the waste generated by the electrode wire cutting will be discharged during the zinc gasification, so as to ensure the smooth and orderly processing of the workpiece by the electrode wire. Compared with brass H65 and H63 electrode wires, the workpieces processed by high-zinc-copper alloy electrode wires have higher precision, smoother surface and improved cutting efficiency. However, during the processing of co...
