NICKEL BORON

Nickel Boron is the top of the line coating, with its superbly smooth finish. It is engineered to minimize on friction by cutting down the surface to surface contact between sliding parts. This finish not only reduces the friction, but it also dissipates heat, allowing for the least wear and tear.
