Ti 6Al-4V Eli (Grade 23) Machining

Ti 6Al-4V Eli (Grade 23)

Ti 6Al-4V Eli, also known as Grade 23, is a popular titanium alloy, ideal for parts that require strength and toughness while remaining lightweight. It is extremely biocompatible, making it the material of choice when fatigue and corrosion resistances are necessary. Ti 6Al-4V Eli’s higher oxygen content results in more ductility and fracture resistance than Ti 6Al-4V, but is slightly less strong.

Ti 6Al-4V Eli has a machining cost factor of 6.0 when compared to steel 12L14. It can be hot and cold formed, heat treated, annealed, forged, and aged. Ti 6Al-4V Eli is considered fairly weldable.
