    WallCarb™ HVOF Powders

    Wall Colmonoy introduces WallCarb™ HVOF Carbide Powders, specially formulated for thermal spray applications. These powders deliver dense, hard coatings characterized by low porosity and superior wear and corrosion resistance. With their spherical, spray-dried, and sintered design, WallCarb™ HVOF Carbide Powders ensure high deposit efficiencies and consistent application parameters, leading to smooth coatings that minimize finishing and grinding times.

    WallCarb™ HVOF Powders are available in 5 kg bottles, with micron sizes of either 15–45 or 10–38, specifically designed for use with HVOF systems.
