Tungsten Carbide
Durable Tungsten Carbide
for Extreme Service Applications
Removing Technological Barriers
Since 1910, CoorsTek has created technology-enabling materials to
solve every day technical problems. We have been manufacturing
tungsten carbide materials for over 25 years, continuously
enhancing and expanding our line of materials to meet the growing
needs of industry.
Material properties of tungsten carbide vary depending on the
binders (substances that “bind” the tungsten carbide particles).
CoorsTek offers several different binder compositions to optimize
hardness, impact resistance, chemical/corrosion resistance, and
other physical properties.
CoorsTek offers many grades of tungsten carbide, and our
Tungsten carbide provides exceptional performance engineers will work with you on finding the most suitable material
in many severe-service applications: for your application. The chart below provides data on some of our
more common tungsten carbide materials.
