EOS Titanium Ti64
Material Data Sheet
EOS Titanium Ti64
EOS Titanium Ti64 has a chemical composition corresponding to ASTM F1472 and ASTM F2924. Ti64 is well-known light alloy, characterized by having excellent mechanical properties and corrosion resistance combined with low specific weight. Ti64 material is ideal for many high performance applications. Parts built with EOS Titanium Ti64 powder can be machined, shot-peened and polished in as-built and heat treated states. Due to the layerwise building method, the parts have a certain anisotropy.
- Excellent mechanical properties and corrosion resistance
- Low weight & biocompatibility
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
