タイトルまたは説明

CD wire drawing die is used cobalt element and diamond powder as raw material, produced in the high temperature, high pressure conditions. So he heat resistance is as high as ***0 ℃.The hardness of CD die is after that of natural diamond die. Thanks to the well-distributed density and crystallinity, and reasonable molecular arrangement, the situation of material-drop and grain roughness reduce.CD dies not only have the same wear resistance and hardness as natural diamond die,but also have have pretty good roundness. Its fine particle crystallization make the die produces high  brightness.It is suitable for small and medium-sized wire diameter drawing.
