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.
