Tungsten Carbide Powders

What Is Tungsten Powder Used for?

Tungsten powders are known for their hardness, superior density properties, and wear resistance. Tungsten carbide powders are commonly used in applications involving sliding wear erosion, impingement, abrasion, and fretting wear while providing low-temperature wear properties.  Applying a tungsten carbide thermal spray powder creates a dense, hard, and tough coating that is well suited for industries such as petrochemical and marine.

Common applications

  • Oilfield drilling:  Well headgates, subsea gates, mud motor rotors, frac valves
  • Aviation: landing gear, actuators, flap tracks, bearing journals, mid spams
  • Power generation: industrial gas turbine, hydroelectric Pelton buckets, nozzles, blades, exhaust fans
  • Petro Chemical: pumps, impellors, cat cracker bottom pump housing, wear rings, cast rings, plungers, plastic extruders, bearing journals, ball valves, hydraulic rods, conveyor screws
  • Gas Compression Applications: Compressor rods
  • Medical: Surgical tools
  • Diamond tool applications
  • Metal Processing: rolls, steel mill rolls, paper mill rolls, bearing journals, guides
  • Automotive: transmission shifter forks, synchronizer rings
