Aluminum Bronze

Aluminum Bronze is an excellent and versatile material for use in highly corrosive environments requiring high mechanical properties. Used extensively in the aircraft, marine and petrochemical industries, aluminum bronze is preferred for the toughness, corrosion resistance and strength presented by up to 11% aluminum in this alloy. These alloys exhibit high resistance to corrosion in difficult atmospheric conditions and sea water due to the presence of a performance-enhancing surface layer of aluminum oxide.

    Typical Applications:
  • Heavy Duty Pump Applications
  • Cams High Strength Bushings and Gears
  • Aircraft Landing Gear Components
  • Cams
  • Sleeve Bearings
  • Gears
  • Valve Guides
