Abstract

The invention discloses a high zinc-silicon-boron-ferro-copper alloy. The copper alloy is characterized by comprising the components in percentage by weight: 38.0-44.0 percent of zinc, 0.001-0.5 percent of silicon, 0.001-0.025 percent of boron, 0.005-0.5 percent of ferro, 0.001-0.01 percent of rare earth, 0.0005-0.1 percent of other element including at least one of phosphorus, magnesium, potassium, calcium, sodium, aluminum and barium, and the balance of copper and inevitable impurity elements. The copper alloy is used for manufacturing a cutting line for one-way wiring; compared with the prior art, the copper alloy has the advantages that the manufactured cutting line for one-way wiring is high in mechanical performance, stable in discharging performance and high in cutting speed; the cutting line is simple in processing procedures, wide in application and low in cost and has wide market prospect.

Description

technical field [0001] The invention relates to a copper alloy, in particular to a high-zinc (38.0-44.0 wt %) silicon-boron-iron-copper alloy for manufacturing a cutting wire for unidirectional wire feeding. Background technique [0002] The unidirectional wire electric discharge machining method is a precision machining method developed rapidly in recent years. It has been more than 30 years since it was introduced into China in the 1980s. At present, more than 80% of the cutting wire materials used in the Chinese mainland market use ordinary brass alloy cutting wires, and a small part of them are used for one-way wire walking. Manufacturers use composite copper alloy cutting wires, but with the intensification of market competition and the increase in human resource costs, more and more users hope that cutting wire manufacturers can provide cutting wires with lower cost, higher efficiency and better performance. Wire. [0003] As we all know, my country is a copper-poor ...
