Why Use Bronze Alloy 943? 

This bronze alloy is perfect for bearing applications loss of lubrication is possible. Typical uses include: 

  • Bearings
  • Bushings
  • Railroad Components

Bronze Alloy 943 performs well in demanding environments where foreign matter like dirt and debris may be present. By being malleable, it can envelope foreign material like dirt and debris. As a result, the wear surface of a mating part such as a shaft is protected.
