Helicopter

Aubert & Duval is a recognized stakeholder that plays a major role in the supply of high performance materials and stamped parts for helicopters.

High performance parts for structures
The main transmission box of a helicopter suffers a very high torque effect and major vibrations. In order for these to offer the best solidity guarantees, the component parts are produced from grades such as GKP®, GKH®, FND® or FDG® to which thermal nitriding or cementation treatments are applied.

Our offer
Bars intended for:

• the main rotor,
• the 42° and 90° transmission systems,
• the main structure,
• or for other applications with the same requirements.
