Abstract Arcam Ti6Al4V ELI (Grade 23) is a titanium-based alloy that is used for the production of additively manufactured components using electron beam melting (EBM). This alloy offers the best all-round performance for a variety of weight reduction applications in aerospace, automotive, and marine equipment. It also has numerous applications in the medical industry. Arcam Ti6Al4V ELI is very similar to Arcam Ti6Al4V, except that Arcam Ti6Al4V ELI contains reduced levels of oxygen, nitrogen, carbon, and iron. These lower interstitials provide improved ductility and better fracture toughness. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and tensile properties. It also includes information on machining and joining. Filing Code: Ti-178. Producer or source: Arcam AB (a GE Additive Company).
