Constellium SE has completed a major €30 million investment at its Singen plant in Germany, inaugurating new finishing lines dedicated to high-quality aluminum foilstock for battery applications. The project, carried out in partnership with Lotte Infracell, a subsidiary of Lotte Aluminium, included the construction of a new building, installation of advanced equipment, and commissioning of production in November 2025. The expansion also features a solar power system expected to generate approximately 760,000 kWh of renewable energy annually, supporting Constellium's commitment to sustainability. This development reinforces the Singen facility's role as a center of excellence for high-performance aluminum products, particularly in supporting the growing e-mobility and sustainable energy markets.
