類等の葉材として利用されている。(Prior Art) Conventionally, as copper used for electrical purposes and chemical industries, there are high purity copper such as oxygen-free copper and tough pitch copper specified in JIS H3100. Such high-purity copper has excellent electrical and thermal conductivity, as well as good malleability, drawability, weldability, corrosion resistance, and weather resistance, so it is used for electrical and chemical industries, etc. It is used as leaf material for various parts, products, and equipment in a wide range of fields.

特長を失わせるという問題点があった。(Problems to be Solved by the Invention) However, although the above-mentioned high-purity copper has excellent plastic workability such as malleability and drawing workability, it has poor machinability during cutting. , Since chips are likely to form continuously during cutting, there is a problem that the manufacturability of parts (products) by cutting is not very good, and in addition, the life of the cutting tool is short. was there. In particular, in the case of oxygen-free copper, the amount of oxygen is regulated to 10 ppm or less in order to have excellent electrical and thermal conductivity, so machinability during cutting is poor.
Although increasing the amount of oxygen improves machinability, it lowers electrical conductivity and thermal conductivity, causing the problem of loss of the characteristics of oxygen-free copper.

なっていることが明らかである。As shown in Table 1, electrolytic copper (No. 1) has excellent hot workability and electrical conductivity, but is significantly inferior in machinability. Furthermore, when P and Zr were added to improve hot workability (No, 2.3), the machinability was considerably poor. Furthermore, it is clear that when PB was added to improve machinability (No. 4), hot workability deteriorated considerably.
