Sumicrystal CD Blanks
  • Sumicrystal CD (single crystal) diamond blanks are used in wire drawing dies.
  • CD diamond blanks offer very uniform blank to blank properties which are critical in wire die strings.
  • CD diamond blanks also offer superior fracture strength, high hardness and high thermal conductivity. All these properties significantly affect the life and performance of diamond wire dies. CD blanks have shown superior die life over a wide variety of ferrous and non-ferrous wire types.
  • Special shapes and sizes are available in addition to the standard shapes shown below:
