SumiDIA WD Blanks

• Sumitomo has recently introduced a new "high density" PCD wire die blank. These new die blanks contain more diamond and less metal catalyst resulting in a PCD material which has a significantly higher abrasion resistance.

• There are three new series of blanks and all are available with 1, 3, 5,12 and 25 micron diamond.

  • WD700 series is free standing cylinder of PCD diamond (no carbide support ring).
  • WD800 series is the same as the WD700 series but it has been made thermally stable to 1,000°C. This is important when mounting the die blank with high temperature brazing alloy or drawing wire in a high temperature condition.
  • WD900 series is a PCD cylinder with a tungsten carbide support ring.
