明は、第二の目的を達成する為にＰｂ 、 Ｔｅ 。The present invention described above makes it possible to obtain an alloy with good corrosion resistance and free machinability. However, when attempting to further improve the hot workability required for eyeglass parts among decorative items, the free machinability and corrosion resistance deteriorate. It has been difficult to obtain an alloy that is easy to mold and satisfies the characteristics of corrosion resistance, free machinability, and workability. Therefore, in order to achieve the second objective, the present invention uses Pb and Te.
