Aviation boilerwork for high temperature environments

ALSENAM has an extensive experience in using hard metals to manufacture hot parts, in particular for engines: engine support, jet nozzle, guard, combustion chamber. ALSENAM has been qualified by key customers for associated special techniques such as: cutting, machining of critical zones, welding, dye penetrant testing, X-ray testing, etc. The destructive and non-destructive test laboratory, the boilerwork staff’s knowledge of these materials, make it possible for ALSENAM to fulfil the most demanding specifications.

Sheet metal part prototyping

The agile organisation and the wide variety of know-hows within ALSENAM makes it possible to produce single metallic parts, such as propotype or mini-series. ALSENAM produces prototypes designed by its customers, but also advises them during the design phase.

ALSENAM accompanies several schools and research centres, contributing to the early stages of their projects, with its expertise in sheet metal work, boilerwork and welding.

Repair, MRO

ALSENAM helps its customers with their part appraisal and repair requirements. ALSENAM advises on the choice and implementation of destructive and non-destructive testing (dye penetrant, X-ray, dimensional, leak testing) and carries out repairs on a wide range of materials: stainless steel, inconel, titanium, aluminium, etc. ALSENAM works on welding, dimensional conformity adjustments, straightening, element replacement (clamps, bossing, fins, etc.), milling repairs, riveting assembly, nitrogen insertion, and the control of the specific subcontracting chain.
