Kennametal Tungsten Carbide Powders
In compression, the strength of tungsten carbide (WC) is greater than any material ever known. Combined with its high thermal conductivity, intense strength, and extreme stiffness, tungsten carbide is the choice material for all types of metal forming and cutting tools.
What Makes Kennametal Powders Different?
Kennametal provides a variety of tungsten carbide powders. Exacting quality control, large uniform batches, high purity, and particle size uniformity enhance its desirability by manufacturers of cemented tungsten carbide.
Produced by Kennametal’s patented thermit process, Macrocrystalline tungsten carbide powder is ideally suited to all diamond tool applications. Low internal porosity combined with high packing density results in a tool with extreme wear resistance levels.
- Monocarbide, fully carburized and dense
- No undercarburized W2C phases
- Large macro-sized crystals
- High thermal stability
- Uniform internal structure
- Excellent wetting properties
- Available in a wide range of sizes from 40 US mesh to micron sizes
Conventional Carburized WC
Produced by solid carburization of tungsten powder, this polycrystalline material is used in diamond tools as a harder and wear rate modifier. Once mixed with cobalt and binder, tungsten carbide is pressed and sintered. Sintered tungsten is used to cut steel, drill circuit boards and a multitude of other high tech applications in the automobile and aerospace industries, and beyond.
- Loosely agglomerated
- Available in several grades from 0.8 micron to 4.8 micronmesh to micron sizes
Chill Cast Carbide KF-110F
This material is produced by the high temperature reaction of tungsten and carbon via a casting process. Blends are reacted in graphite, cast, and then crushed to size. Cast tungsten carbide is among the hardest and most abrasion resistant materials used in diamond tooling.
- Used extensively as wear rate modifier in hot-press bonding system & infiltration process
- Available from 40 US mesh (420 micron) down through -400 mesh (37 micron)
All powder is commercially uniform in purity. The chemical and physical analyses are determined for each production lot of powder by using commercially accepted methods. The results of all relevant tests are reported to the customer on a Certificate of Analysis.
