Constellium SE CSTM

CSTM Company Overview

Constellium SE is a global manufacturer of aluminum products and solutions, serving customers across the aerospace, automotive, packaging, and industrial markets. The company focuses on the development and production of high value‑added aluminum rolled products, extrusions, and structural components that are engineered for lightweighting, performance, and recyclability. Its revenue is primarily driven by long‑term supply relationships with original equipment manufacturers (OEMs) and tier‑one suppliers in transportation and packaging industries.

The company was established in 2011 through the combination of aluminum rolled and extrusion product businesses formerly owned by Rio Tinto’s Alcan unit and legacy European aluminum operations originating from Pechiney. Since its formation, Constellium has positioned itself as a technology‑driven materials supplier with an emphasis on innovation, sustainability, and closed‑loop recycling systems, particularly in automotive and packaging applications.
