EOS Titanium Ti64 Grade 23

EOS Titanium Ti64 Grade 23 is a Ti6Al4V alloy with lower amount of oxygen and iron compared to the standard Ti64 alloy. The chemical composition corresponds to ASTM F136 and ASTM F3001. The material is well-known for having excellent mechanical properties: low density with high strength and excellent corrosion resistance.
Compared to Ti64, Ti64ELI has better elongation and toughness, but lower strength. Generally, Ti64ELI alloys are considered to be biocompatible and have low specific weight compared to CoCr alloys.
Parts built with EOS Titanium Ti64 Grade 23 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 23 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.
