Constellium (NYSE: CSTM) is a global leader in the development and manufacturing of high value-added aluminium products and solutions. We design and manufacture advanced alloys and engineered solutions for a range of applications, such as cars, beverage cans, airplanes and more.

Constellium’s story dates back more than a century, with our roots in the aluminium pioneers Pechiney, Alcan, and Alusuisse. Through constant innovation, we go beyond the material to create with our customers endless possibilities. From beverage cans to pickup trucks, fuselages to space launchers, our R&D centers constantly explore the many ways to transform this material and help build a more sustainable future.

Much more than a simple commodity, aluminium will play a major role in the lighter, faster economy of tomorrow. So will Constellium, as we strive to be the most exciting, value-adding business in the industry.


    Specific alloy design for laser powder bed fusion and post-processing that exhibit improved geometric control and robust heat treatment...

  • High Performance

    - Mechanical properties outperform aluminum silicon alloys and 6061 T6

    - High thermal and electrical conductivity

    - Thermal stability allowing service temperatures above 200°C/400°F

    - Excellent corrosion performance. 


    - Almost any LPBF component designed for 6061 or Al-Si alloys such as AlSi10Mg and F357

    - New AM designs leveraging the unique properties of Aheadd® CP1: heat exchangers, RF components, semiconductor tooling…


    - Nominal particle size 20-63µm. Not classified as hazardous goods for transport and storage

    - Powder compatible with major L-PBF machines: EOS, SLM Solutions, Renishaw, 3DS, ADDUP)

    - Single gas atomized powder (not a composite blend) for more robust recycling

    Game-changing thermal stability

    - In addition to outperforming Al-Si alloys and 6061, Aheadd CP1 will not soften over thousands of hours at service temperatures as high as 250-300°C.

    - Thermal stability is due to the alloy system: Zr and Fe diffuse extremely slowly in aluminum, unlike conventional alloying elements Si, Mg, Zn, Cu, Li.

    Robust, high-productivity processing in laser powder bed fusion

    - No volatile elements such as Zn and Mg for improved melt pool stability

    - Geometric distortion is minimized through low residual stress (typical as-built yield stress <150MPa)

    - No cracking during LPBF process. As-built tensile elongation >20%

    - Thermal exposure during AM build cycles has no impact on Aheadd CP1 structure and properties (thermal exposure during build cycles at 100-200°C impacts microstructure of conventional aluminum systems, resulting in microstructure and property variations between the first and last layers to be built)

    - As-built surface roughness Ra below 10µm demonstrated for 35° downskin using 60µm layers (EOS M290)

    AHEADD(R) HT1 is the most suitable additive manufacturing alloy for applications which need high strength and service
    temperatures up to around 260°C/500°F....

  • The high thermal stability of AHEADD(R) HT1 makes it as an ideal choice to replace many titanium applications to reduce the component weight and cost. The higher thermal conductivity of aluminium over titanium may bring additional advantages.
