As an electrode wire, this is run to apply a voltage in the machining fluid between the workpiece and the workpiece to repeatedly generate pulsed discharge,
This discharge energy is used for wire electric discharge machining for processing a workpiece into a predetermined shape, and the wire electric discharge machining is widely used in precision machining such as a press die.
For the electrode wire, a thin wire having a diameter of 0.01 to 0.35 mm, such as brass, copper, tungsten, and molybdenum, is used. Of these, brass (Cu—Zn-based alloy) wire is Zn.
In order to increase the strength, the tensile strength is twice or more that of the pure copper wire, and Zn as an alloying element acts to increase the discharge frequency and the vaporization explosive force, so that high-speed machining is possible. Moreover, since brass is relatively inexpensive, it can be disposable and production control is easy.

用いた放電加工用電極線を提供することを目的とする。In recent years, wire electric discharge machining has been widely used, and as a result, there has been a strong demand for improved machining accuracy, improved machined surface smoothness, and increased machining speed. The processing accuracy is improved by thinning the electrode wires. The smoothness is deteriorated by the vibration of the electrode wire during electric discharge machining, and is improved by increasing the tension of the electrode wire. In addition, the vibration of the electrode wire at the time of electric discharge machining increases as the electric discharge machining speed increases. For this reason, in order to realize machining accuracy, smoothness, and high-speed machining in wire electric discharge machining, it is essential to develop an electrode wire that can withstand high tension even if the wire is thinned. However, conventional wires such as copper and brass have insufficient strength and cannot be applied with high tension at the time of electric discharge machining when they are thinned, so that there is a problem that the smoothness of the machined surface is poor or high-speed machining cannot be performed. In addition, wires such as tungsten and molybdenum have no problem in strength, but have drawbacks in that they are inferior in wire drawing workability, so that the processing cost is several tens of times that of copper and brass, and lacks practicality. An object of the present invention is to provide an inexpensive copper alloy wire rod capable of withstanding high tension even when the wire is thinned and an electrode wire for electric discharge machining using the wire rod.

It is manufactured by performing various steps of cold working. It can be manufactured even if the secondary cold working is omitted. The crystallized Cr in the ingot is drawn into a fibrous shape in the longitudinal direction in the cold working step. The Cr crystallization expanded into a fibrous form significantly improves the strength and heat resistance of the wire. Cr content is 10wt% or more and 30wt%
The reason specified below is that if the content is less than 10% by weight, the effect cannot be sufficiently obtained, and if the content exceeds 30% by weight, the effect is saturated, which is uneconomical and lowers the cold workability. Zn improves the strength and the electric discharge machining property. EDM has the following characteristics: discharge frequency and vaporization explosive force,
It is evaluated in terms of discharge stability. Zn content of 10 to 3
The reason for specifying 5 wt% is that if it is less than 10 wt%, the effect of improving the discharge machinability of Zn is not sufficiently exhibited, for example, the discharge frequency during electric discharge machining is not sufficiently increased. Also 35wt
%, The cold workability decreases, the number of intermediate annealing increases, and the productivity deteriorates.

P, Mg, Be, Al, Ni, Ti, Sn, Zr, C
o, at least one of the 11 elements of Ag is contained. Among them, Si contributes to solid strength or precipitation to improve strength. As the content increases, the electrical conductivity and workability decrease. P contributes to the improvement of the strength by increasing the hardenability. When the content increases, the compound containing P segregates at the grain boundaries, and the corrosion resistance and the electrical conductivity are reduced. Mg traps S inevitably mixed as an MgS compound and precipitates in the matrix, contributing to an improvement in strength. When the content increases, a eutectic compound of MgCu 2 is formed and 722 ° C.
The hot workability described above deteriorates. Be is dissolved or precipitated and contributes to strength improvement. When the content increases, the processability decreases. In addition, Be is expensive, resulting in an increase in cost. Al, Ni, Ti, and Sn each contribute to strength improvement. When the content increases, the conductivity significantly decreases in each case. Zr contains Cu 3 Zr in the matrix.
It precipitates finely as a compound and contributes to improvement in strength and heat resistance. As the content increases, the electrical conductivity decreases. Co
Promotes precipitation of Cr to improve strength and conductivity,
Further, the heat resistance is improved by preventing the crystal grains from becoming coarse. When the content increases, the processability decreases. Ag contributes to improvement in strength and heat resistance. When the content increases, the conductivity decreases, and the melting point decreases, thereby deteriorating hot workability. Further, Ag is expensive, which leads to an increase in cost. Since the electric discharge machining is performed while repeating the pulsed electric discharge, the improvement of the heat resistance and the conductivity of the electrode wire effectively affects the electric discharge machining characteristics.

In any case, if the content is less than 0.005 wt%, the respective effects are not sufficiently exhibited. On the other hand, if the total content of the 11 elements exceeds 0.5% by weight, workability, thermal conductivity, conductivity, corrosion resistance, etc. are reduced, and the raw material cost is disadvantageous. Therefore, the content of the 11 elements is 0.5 wt% in total.
Hereinafter, it is individually limited to 0.005 wt% or more.

The elements B, N, and C increase the frequency of generation of crystal nuclei during casting to make the ingot structure finer, and as a result, crystallized substances of Cr are more uniformly dispersed, and properties such as strength and heat resistance are obtained. Is improved. The B, N, and C elements contain at least one of these elements. The reason for specifying the total content to be 0.5 wt% or less and individually 0.005 wt% or more is that each element is When the content is less than 0.005 wt%, the effect is not sufficiently exhibited, and when the total content exceeds 0.5 wt%, B, N,
This is because a compound is generated between C and Cr and the like, and the workability is reduced.

This is because a large amount of the crystallized Cr was stretched into a fiber in the longitudinal direction and was uniformly dispersed. In particular, in Nos. 4 to 6 each containing a small amount of C, B, and N, the processing speed was further improved because the Cr crystallized substance was more finely dispersed.
