Our 3750 powder is an aluminum bronze powder specially processed by a proprietary process to work as a self-bonding one-step material. 3750 coatings offer good wear resistance and are used for soft bearing applications.

“One Step” powders are specially manufactured to combine a bonding mechanism into each powder particle.

  • Proprietary “One Step” design eliminates the need for bond coat application.
  • Balanced particle distribution maximizes spray efficiency and minimizes fuming.
