Constellium has entered into a strategic partnership with industrial 3D printing specialist EOS to accelerate the development and industrial adoption of advanced aluminium alloys for additive manufacturing, strengthening the availability of high-performance materials for serial production across multiple industries.

The collaboration combines Constellium’s expertise in aluminium alloy development with EOS’ industrial metal additive manufacturing technologies. By working together, the companies aim to shorten material qualification cycles, provide customers with validated material and process combinations, and speed up the commercialisation of new aluminium applications.

A key milestone of the partnership is the integration of Constellium’s Aheadd® CP1 alloy into the EOS materials portfolio. The material will be marketed as EOS Aluminium Constellium CP1 and is scheduled to become available through EOS from August 2026. The alloy has been developed specifically for additive manufacturing and offers a combination of high strength, good thermal conductivity and excellent crack resistance, making it suitable for demanding applications with complex geometries.

The partners will also collaborate on accelerating the industrialisation of Al5X1, Constellium’s next-generation high-performance aluminium alloy designed for advanced additive manufacturing applications.

According to Ludovic Piquier, Senior Vice President, Manufacturing Excellence and Chief Technical Officer at Constellium, the partnership will help manufacturers reduce qualification times, improve production efficiency and expand the use of lightweight aluminium components. The initiative is expected to support growing demand for additive manufacturing solutions in sectors including aerospace, automotive, defence, industrial equipment and energy, where complex, lightweight and high-performance parts are increasingly required.
