PCD AND ITS APPLICATIONS
Polycrystalline diamond blanks feature a unique combination of two materials -
polycrystalline (synthetic diamond) and a tungsten carbide substrate.
The two materials are inseparably joined as an integral blank, by an advanced high temperature,
high pressure process. These blanks are then bonded to tool shanks, wear parts, or
carbide inserts. The resulting composite material possesses the best qualities of
both materials, the high hardness and excellent wear resistance of diamond, as well as
the toughness and bondability of tungsten carbide, and has been proven to be effective
for a wide range of non-ferrous and non metallic machining applications.
