Compared with cemented carbide, polycrystalline diamond has a tensile strength of only 70％ of that of conventional hard alloys, but is 2.5 times that of hard alloys. In this way, the polycrystalline diamond mold has more advantages than the cemented carbide mold. The wire drawing die made of polycry......
