A "bridge" between design and manufacture, ATMOSTAT oversees a complex range of special processes which require manufacture, assembly of rare materials (beryllium and its alloys, tantalum, niobium, etc.) and substantial checks.

ATMOSTAT’s business has three main strands, covering the whole life-cycle of a system: products, bespoke designs and advice.

ALCEN works in four domains: defence & security, energy, medical and aeronautics.

Its ambition is to establish a constant innovation policy in these domains, primarily applied to its own products and services.

Wherever possible, they offer innovative solutions.

It organizes its teams in structures that are both independent and coordinated, set up around top-level, fully accountable members of staff.
