Ti 6al 4v Titanium
(GRADE 5)

The alloy is the most widely used high strength titanium. Ti-6Al-4V (Grade 5) combines mechanical strength and low density (4.42 kg/dm³) with excellent corrosion resistance in many different environments. Grade 5 titanium is heat treatable (solution heat treatment plus ageing) in sections up to 25mm and can be employed up to around 400°C.

We stock this alloy in the following: bar, wire sheet, extrusions, forgings, seamless pipes and tubes.

Machinability

The alloy can be machined using practices for austenitic steels with slow speeds, heavy feeds, rigid tooling and large amounts of non-chlorinated cutting fluid.

---

Weldability

The alloy benefits from good weldability in the annealed condition or the solution and partially aged condition, with ageing completed during the post-weld heat treatment. Precautions must be taken to prevent oxygen, nitrogen and hydrogen contamination. Fusion welding by inert gas welding of the molten metal and the adjacent heated zones using a trailing shield is acceptable. Other welding practices include spot, seam and flash welding performed without resorting to protective atmospheres.
