PDC Substrate

Polycrystalline Diamond Compact, also known as PDC, composes of polycrystalline diamond layer and carbide substrate, is one kind of super hard composite material which is sintered under the condition of high temperature and pressure. PDC has excellent abrasion resistance, good impact resistance and thermal stability. It has been widely used in production of oil drill bits, coal and other geological drill bits and cutting tools. Tungsten carbide substrate is an indispensable part of PDC. We produce a broad range of carbide PDC substrates that are suitable for various PDC. Our company also provides custom sizes to meet non-standard requirements.

This tungsten carbide substrate is used for making PDC drill bits and oil-field diamond compact, such as oil or gas drill bit, rock drill and coal mining drill bit, and also could be used for diamond tools for cutting, grinding, polishing. Carbide PDC substrate are mainly used for making PDC for mining and for machinery tools.
1. PDC for Mining
This tungsten carbide substrate is suitable for geological drilling coal and soft or medium hard rock formations. It has a high resistance to impact toughness and thermal stability. The maximum heat-restraint temperature can be up to 750°c (two minutes).
2. PDC for Machinery Tools
With higher hardness, wear resistance and cutting precision, PDC substrate is suitable for cutting high hardness alloy, wood and ceramic such as non-metallic, non-iron metal and metal materials. The types and shapes of tungsten carbide substrate can be designed by customers, such as rectangular, triangle, sector and other special shapes.
