Constellium SE
A maker of high-value aluminum products, Constellium supplies the aerospace, automotive, and packaging industries — its metal ends up in aircraft parts, car bodies, and the cans and closures for drinks and food. The company was formed in 2011 when Rio Tinto sold its Alcan Engineered Products business, whose roots reach back more than a century to three aluminum pioneers: Pechiney, Alcan, and Alusuisse. Its name plays on the word 'constellation,' reflecting how those historic companies came together.
