Aircrafts

There are 100s of use cases of our products in an aircraft, be it for components facing mechanical wear and friction or temperatures variation or corrosion (bushings, bearing cages, actuators…), be it for free-cutting materials for high performance connectors, be it for cabling, and many more cases.

Helicopters

Our products are used in helicopters, for example K7 in flap systems and bushings, and many of our free-machining alloys being used in numerous connectors.

Space launchers and satellites

Our products with high mechanical characteristics such as Hardiall® are used for high-reliability and light-weight parts in satellites, as well as our electronic shielding and high-quality alloys for electronics.
