Annealing Temperature 700-785°C.

Applications: Blades/Discs/Rings/Airframes/Fasteners/Components/Vesseles/Cases/Hubs/Forgings/Biomedical implants.

Biocompatibility:

Excellent, esp when direct contact with tissue or bone is required. Ti-6Al-4V’s poor shear strength makes it undesirable for bone screws or plates. It also has poor surface wear properties and tends to seize when in sliding contact with itself and other metals.

Surface Treatments such as nitriding and oxiding can improve the surface wear properties.
