Bronze in Aerospace

Atlas Bronze offers a range of copper alloys for aerospace applications. Aerospace alloys are used for a wide variety of applications, such as:

  • Landing gear bushings and bearings
  • Hydraulic actuators
  • Flight controls
  • Static joints
  • Helicopter controls
  • Flight instruments
  • Flap and slap carriages
  • Wheel bearings
  • Missile vane controls
  • Warhead delivery systems
  • Ground equipment
  • Hatch and door mechanisms
  • Steering joints

  • Thanks to their high mechanical properties (low friction coefficient, resistance to corrosion, stability at extreme temperatures), our copper based alloys have become a reference in the aerospace applications. We provide all these companies, and their repair services all over the world, with a wide range of products (rings, discs, etc …) according to customer’s drawings mainly designed for bushings and bearings for landing gear and breaking systems for aircraft and helicopters.
