Advantages of Nickel Boron:

Nickel Boron coatings are columnar in growth resulting in a distinct nodular topography which serves to reduce surface to surface contact of two mating / sliding surfaces reducing drag / friction. The nodular structure dissipates heat at greater efficiency due to greater surface area.

  • Harder surface results in less wear
  • Reduced Friction
  • Reduced Heat
  • Operates with little to no lubricant
  • Easy to Clean
