Introduction

Titanium Alloy

EOS Titanium Ti64 is a Ti6Al4V alloy. This well-known light alloy is characterized by having excellent mechanical properties and corrosion resistance combined with low specific weight. The ELI version (extra-low interstitials) has particularly high purity.

Key Benefits
Light weight with high specific strength (strength per density)
Corrosion resistance
commonly used in biomedical applications
Laser-sintered parts fulfil requirements of ASTM F1472 (for Ti6Al4V) and ASTM F136 (for Ti6Al4V ELI) regarding maximum concentration of impurities
Very good bioadhesion (cell growth tested with good results)
