SN Auvergne Aeronautique

 

Sheet metal work and forming activities

SN Auvergne Aeronautique specialises in the production of parts for sheet metal work and forming activities for large-scale civil and military aerospace programs.

The company has several decades of experience and the products it makes are found in a wide range of flagship units such as the Ecureuil, Super Puma and Tiger helicopters, as well the Airbus from the A320 family.

As well as sheet metal parts from light alloys and hard metals, SN Auvergne Aeronautique, which has 600 employees in France (Aulnat Site) and Morocco (Casablanca Site), also has the capacity to offer complex sub-assemblies.

The acquisition of this subsidiary allows the Figeac Aero Group to integrate a strategic competence in the production line of metallic parts for large clients. These parts are made through metal sheet forming, metal cutting and welding processes that require knowledge, know-how and industrial equipment which are different to those used for machining.
