Titanium Alloy: Ti-6Al-4V

Ti-6Al-4V is the nominal composition of titanium alloy Grade 5 which is the most widely used titanium alloy grade. A lot of other titanium alloys are improved version of this grade. It accounts for 70%~80% of world’s titanium market.  Ti-6Al-4V, UNS R56400, is a typical alpha+beta alloy which is primarily furnished in annealed condition. It has useful creep resistance up to 300°C [570°F] and excellent fatigue strength. It can also be used for cryogenic applications at extremely low temperatures.

Ti-6Al-4V has good corrosion resistance to atmosphere, oxygen, seawater, as well as pure hydrocarbons. It can be produced by metal or remelting process such as vacuum arc remelting(VAR), electron beam(EB), and plasma arc hearth melting(PAM), etc. Ti-6Al-4V alloys can be used for a variety of applications such as aircraft gas turbine disks and blades, airframe structural components, oil and gas offshore platforms, bolts & nuts, and surgical implants, etc. They are available in product forms of strip, sheet, plate, bar, rod, tube, fitting and forging.
