Why this combination

Why Titanium Grade 5 in bars

Ti-6Al-4V alpha-beta alloyTensile strength about 900 MPa at 4.43 g/cm³Excellent fatigue and corrosion resistanceStandard for aerospace and high-performance fasteners

Aluminium and vanadium roughly double the strength of commercially pure titanium while keeping low density.

It is chosen where weight and strength matter more than the slightly better corrosion resistance of Grade 2.

Specification

How to specify Titanium Grade 5 bars

Round bars about 3 – 500 mm diameter; hex 6 – 100 mm A/F; square and flat sections to order; lengths 3 – 6 m random or cut to size
