ADDITIVA_Titanium Ti6Al4V_rev009.docx
Titanium Ti6Al4V is a lightweight alloy renowned for its excellent mechanical properties, including fracture toughness,
fatigue strength, and corrosion resistance, together with low specific weight and biocompatibility. Grade 23 differs from
Grade 5 primar ily in its reduced oxygen content (maximum 0.13% in Grade 23), which enhances ductility and fracture
toughness, although it slightly reduces strength. Grade 23 is widely used in fracture - critical airframe structures,
lightweight components for the motorspo rts and aerospace sectors, and surgical implants and medical instruments.
