EOS, Krailling, Germany, has introduced four new metal powders for use with its Additive Manufacturing systems, namely EOS StainlessSteel CX, EOS Aluminium AlF357, EOS Titanium Ti64 Grade 5, and EOS Titanium Ti64 Grade 23. The metal powders have reportedly been tailored to suit a range of applications, including automotive and medical.

Comprehensive data on the material properties of all four metals, which includes the number of test specimens on which the mechanical properties are based as well as scanning electron microscope (SEM) images, are available from EOS.

With over twenty-five years of experience in working with metals, EOS currently offers a range of twenty different metal powders. At EOS Oy in Finland, the company concentrates solely on the development, qualification and quality assurance of metal materials and processes. Hannes Gostner, Director of Research and Development at EOS stated, “At EOS, the development of systems, materials, process parameters, software, and services have always gone hand in hand. All of the elements are perfectly aligned to each other. The result is reproducible high-quality parts at a competitive cost per part. This combination is of crucial importance, particularly for series manufacturing.”

The first new material is the EOS StainlessSteel CX, a new tooling grade steel developed for production with the EOS M 290 that is said to combine excellent corrosion resistance with high strength and hardness. Components made from this material are reportedly easy to machine and enable a polished finish.

The second new material is the EOS Aluminum AlF357, a material suitable for applications that require a light metal with excellent mechanical/thermal strength. Components made from this material are characterised by their light weight, corrosion resistance and high dynamic loading. It has been developed for production with the EOS M 400, but the company intends to make the material available for the EOS M 290 system in the future.

The third new material is the EOS Titanium Ti64 Grade 5 which has been developed for its high fatigue strength without Hot Isostatic Pressing (HIP). It is reportedly suitable for production with the EOS M 290, and also offers corrosion resistance, making it ideal for aerospace and automotive applications.

The final new material is the EOS Titanium Ti64 Grade 23 which has also been developed for its high fatigue strength without HIP and for production with the EOS M 290. When compared to Ti64, the Ti64 Grade 23 offers improved elongation and fracture toughness with slightly lower strength. Thanks to these properties, it is particularly well suited to medical applications.
