EOS Titanium Ti64ELI
Material Data Sheet
EOS Titanium Ti64ELI
EOS Titanium Ti64ELI has a chemical composition and corresponding to ASTM F136 and ASTM F3001. Ti64ELI is well-known light alloy, characterized by having excellent mechanical properties and corrosion resistance combined with low specific weight and biocompatibility. This material is ideal for many high-performance applications. Parts built with EOS Titanium Ti64ELI powder can be machined, shot-peened and polished in asbuilt and heat treated states. Due to the layerwise building method, the parts have a certain anisotropy.
- Excellent mechanical properties and corrosion resistance
- Low weight and biocompatibility
- Parts for medical industry
The EOS Quality Triangle
EOS incorporates these TRLs into the following two categories:
- Premium products (TRL 7-9): offer highly validated data, proven capability and reproducible part properties.
- Core products (TRL 3 and 5): enable early customer access to newest technology still under development and are therefore less mature with less data.
All of the data stated in this material data sheet is produced according to EOS Quality Management System and international standards
