en.Wedoany.com Reported - German EOS has entered into a strategic partnership with French aluminum alloy developer Constellium to expand its aluminum product line for additive manufacturing. Under the agreement, EOS will incorporate Constellium's Aheadd CP1 alloy into its portfolio, marketing it as EOS Aluminium Constellium CP1, and will rename its existing EOS Aluminium Al5X1 grade to EOS Aluminium Constellium Al5X1, while also including this alloy in Constellium's aluminum product line.

Both parties stated that this collaboration extends beyond these two materials, laying the foundation for jointly developing more aluminum alloys suitable for additive manufacturing. EOS noted that the agreement will enable customers of its EOS and AMCM metal systems to use validated alloys with defined process parameters, thereby accelerating certification for industrial-scale production.

"With EOS Aluminium Constellium CP1, EOS Aluminium Constellium Al5X1, and our partnership with Constellium, we are setting a new benchmark for aluminum in additive manufacturing," said Joachim Zettler, Chief Technology Officer of EOS. "Together, we will enable our customers to achieve higher performance, greater production efficiency, and faster adoption in industrial applications."

EOS Aluminium Constellium CP1 is scheduled to be available from EOS starting August 2026. The company reports that this alloy offers higher strength and good elongation compared to conventional aluminum alloys, while simplifying the heat treatment process by eliminating the need for quenching. EOS stated that CP1 also exhibits good thermal stability, corrosion resistance, and electrical and thermal conductivity, and is free of volatile elements such as magnesium and zinc, facilitating stable processing at high laser power. The alloy is easy to anodize and suitable for electrochemical polishing.

EOS lists heat exchangers, semiconductor components (such as heat sinks and wafers), parts exposed to corrosive environments, and lightweight structural components as typical applications for CP1. The company also claims that, thanks to improved processing characteristics, this alloy can serve as a cost-effective, high-performance alternative for many existing AlSi10Mg applications.

EOS Aluminium Constellium Al5X1 retains its positioning as a high-strength, high-elongation, anodizable alloy suitable for aerospace, transportation, and motorsport applications.

"This partnership is a unique opportunity to bring next-generation aluminum alloys to industrial additive manufacturing at scale," said Ludovic Piquier, Senior Vice President of Manufacturing Excellence and Chief Technology Officer at Constellium. "By combining Constellium's alloy development expertise with EOS's leadership in additive manufacturing, we aim to accelerate innovation and unlock new high-performance applications for customers worldwide."
