Tantalum Carbide Powder

We produce and stock customizable tantalum carbide (TaC) powders providing extreme hardness, excellent thermal stability, chemical resistance, oxidation resistance, and wear resistance.

Chemical Formula



Tantalum Carbide


  • Wear surface (wear resistant) parts and coatings. Parts and coatings that undergo fretting, abrasion, cavitation, and particle erosion such as cyclones,  fan blades, turbine blades, liners, chutes, hoppers and feeders.
  • Corrosion resistant coatings. Tantalum carbide is used as a coating for parts requiring  corrosion resistance such as vessels, piping, valves, and turbine blades.
  • Mould coatings. Steel moulds used for aluminum alloys are coated in tantalum carbide to provide a wear resistant surface with a low coefficient of friction mould surface.
  • Additives. Tantalum carbide powder is added to tungsten carbide/cobalt (WC/Co) to inhibit grain growth and increase hardness of the sintered structure.
