Advantages

Why engineers choose Titanium Ti-6Al-4V

Strength-to-weight

Very high specific strength.

Corrosion resistance

Excellent in seawater, chlorides, and many chemicals.

Temperature

Retains strength to roughly 300–400 °C.

Biocompatibility

Widely used for implant-grade alloys when the proper grade and certification are specified.

Design considerations: Expensive stock; slow machining with low thermal conductivity concentrating heat at the tool; galling risk in sliding contact; longer lead times for some sizes.
