The alloy is the most widely used high strength titanium. Ti-6Al-4V (grade 5) combines its good mechanical strength and low density (4.42 kg/dm³) with excellent corrosion resistance in many media. Grade 5 titanium is fully heat treatable (solution heat treatment plus aging) in sections up to 25mm and can be employed up to around 400°C.
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.
The alloy is easily welded in the annealed condition or in the solution and partially aged condition, with aging being completed during the post weld heat treatment. Precautions must be taken to prevent oxygen, nitrogen and hydrogen contamination. Fusion welding can be done in inert gas welding of the molten metal and the adjacent heated zones using a trailing shield. Spot, seam and flash welding can be performed without resorting to protective atmospheres.
