AM 4 AM announces the development of its first aluminum alloy for Additive Manufacturing

After three years in stealth mode, AM 4 AM announces the development of its first metal powder for additive manufacturing. The Luxembourgish startup has developed a high mechanical strength aluminum alloy under the trade name HiPerAl.

According to the materials producer, the new material is a Zirconium derivative of a 7000 series aluminum powder produced by its patented cold plasma treatment. The material’s mechanical properties would be a perfect fit for laser based additive manufacturing processes. The cracks and porosities formation often encountered in the processing of aluminum by AM is erased with HiPerAl allowing high quality parts to be formed, the company says.

 “After three years of development, we are proud to present our first material, HiPerAl. This alloy has been developed in the frame a Horizon 2020 European project and will be dedicated to lightweight applications that require high mechanical properties such as aeronautic, space and automotive. This material has been designed thanks to our atmospheric and cold plasma process which we will use to develop tens of new alloys in the forthcoming years. At AM 4 AM, we consider that the major part of the alloys used in conventional industry are not adapted to additive manufacturing and that we have to develop new ones that will be more suitable to these processes in term of element vaporization, oxidation, reflectivity or cracks formation. HiPerAl has been designed in taking these phenomena into account in order to reach best quality parts for our customers”, Maxime Delmée, CEO and Founder of AM 4 AM comments.

 AM 4 AM will launch the production and delivery of HiPerAl at the beginning of Q1 2023.
