EOS has developed four new metal materials for additive manufacturing (AM): StainlessSteel CX, Aluminium AlF357, Titanium Ti64 Grade 5 and Titanium Ti64 Grade 23. The companies says that the powders are suitable for a range of applications including automotive and medical.
EOS has reportedly assessed the number of test specimens on which the mechanical properties are based on and made detailed scanning electron microscope (SEM) images that provide an insight into the material quality.
- StainlessSteel CX is a new tooling grade steel developed for production with the EOS M 290 that has improved corrosion resistance and high strength and hardness. Components made from this material are reportedly easy to machine and have an improved finish.
- Aluminum AlF357 is suitable for applications that require a light metal with improved mechanical/thermal strength. Components made from this material have light weight, corrosion resistance and high dynamic loading, EOS says. EOS Aluminum AlF357 has been specially developed for production with the EOS M 400, but it is planned to also make the material available for the EOS M 290 system in the near future.
- Titanium Ti64 Grade 5 has improved fatigue strength without hot isostatic pressing (HIP). It is suitable for production with the EOS M 290 and has improved corrosion resistance, making it suitable for aerospace and automotive applications.
- Titanium Ti64 Grade 23 also has improved fatigue strength without hot isostatic pressing (HIP) and for production with the EOS M 290. Compared to Ti64, Ti64 Grade 23 offers improved elongation and fracture toughness with slightly lower strength. It is suitable for medical applications.
