Conventional Tungsten Carbide / Wear Resistant Tungsten Carbide / Cemented Tungsten Carbide
The HeavyStone Surface™
Here at the JIMS, we have partnered with HeavyStone Lab LLC to manufacture functionally graded carbide compacts, produced using HeavyStone Lab LLC’s patented technology. This process for manufacturing functionally graded cemented tungsten carbide turns conventional tungsten carbide into the HeavyStone Surface™ functionally graded carbide with a wear resistant surface and a tough to break core structure. This surface has been found to offer an outstanding combination of wear resistance and fracture toughness, and thus, a better engineering performance with field tests showing results of a 30% increase in footage drilled. HeavyStone Surface™ carbides produced by the JIMS have been widely used in China, the U.S, Korea, Brazil and Europe.
