CD wire drawing die is usedcobalt element and diamond powder as raw material, produced in thehigh temperature, high pressure conditions. So he heat resistanceis as high as 1200 ???.The hardness of CD die is after that ofnatural diamond die. Thanks to the well-distributed density andcrystallinity, and reasonable molecular arrangement, the situationof material-drop and grain roughness reduce.CD dies not only havethe same wear resistance and hardness as natural diamond die,butalso have have pretty good roundness. Its fine particlecrystallization make the die produces high  brightness.It issuitable for small and medium-sized wire diameterdrawing

Hole Size???  From0.04mm-5.00mm
