Tungsten Carbide Powders

Astro Alloys offers tungsten carbide thermal spray powders from Praxair, which are known for their hardness and wear resistance. These 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 spray powder creates a dense, hard and tough coating which is well suited for industries such as petrochemical and marine. Other common applications include:

  • Oilfield drilling:  Well head gates, 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
  • Metal Processing: rolls, steel mill rolls, paper mill rolls, bearing journals, guides
  • Automotive: transmission shifter forks, synchronizer rings
