EOS Titanium Ti64 Grade 5 DMSL on EOS M 400-4; 80 µm Layer Thickness
Categories:	Metal; 3D Printing/Additive Manufacturing Metal; Nonferrous Metal; Titanium Alloy
Material Notes:	EOS Titanium Ti64 Grade 5 is a Ti6Al4V alloy, which is well-known for having excellent mechanical properties: low density with high strength and excellent corrosion resistance. The alloy has low weight compared to superalloys and steels and higher fatigue resistance compared to other lightweight alloys. Parts built with EOS Titanium Ti64 Grade 5 powder can be machined, shot-peened and polished in as manufactured and heat treated states. Due to the layerwise building method, the parts have a certain anisotropy. Heat treatment is recommended to reduce internal stresses and increase ductility. EOS Titanium Ti64 Grade 5 powder can be used on the EOS M 290 with a 40 µm and 80 µm process and on the EOS M 400-4 with an 80 µm process. Main Characteristics: Low weight combined with high strength Excellent corrosion resistance High fatigue resistance compared to other lightweight alloys The parts fulfill chemical requirements for Grade 5 alloy Typical Applications: Aerospace components Automotive components Other industrial applications where low weight in combination with high strength are required Information provided by EOS GmbH (Electro Optical Systems).
