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.
