Grade 5 Ti-6Al-4V Alloy (UNS R56200)
Jan 15, 2026
What is GR5 titanium?
Titanium alloys are known to be light weight alloys with excellent corrosion resistance, very high tensile strength and toughness.
Grade 5 Ti-6Al-4V alloy is the most widely used of all the titanium grades. It is a medium to high strength general-purpose alloy. It is also referred to as an alpha-beta alloy. This alloy is fully heat treatable in sections measuring up to 15mm. It can be heated up to 400°C (750°F), and has good tensile properties at room temperature, creep resistance up to 325°C and very good fatigue strength. It is also known to be highly resistant to general corrosion in sea water.

Fabrication and Heat Treatment
Machinability
Although tough, grade 5 Ti-6Al-4V alloy can be machined using the right quantity of coolant flow, slow speeds and high feed rates. High speed tools should be used for tooling this alloy and the recommended tool types are tungsten carbide designations C1-C4 or cobalt based.
Forming
Grade 5 Ti-6Al-4V alloy can be hot or cold formed. The forming techniques include hydropress, stretch or drop-hammer.
Welding
Weldability of grade 5 Ti-6Al-4V alloy is rated as fair.
Annealing
Annealing can be performed by holding at 732°C (1350°F) between 1/4 and 4 h, then furnace cooled to 566°C (1050°F) followed by air cooling. In case of forgings and bars, furnace cooling is not required.
Heat Treatment
Solution treatment of the material is done at 904-954°C (1660-1750° F) for 2 h, which is followed by water quench process.
Forging
Rough forging of grade 5 Ti-6Al-4V alloy should be performed at 982°C(1800°F), and finished at 968°C (1750°F).
Hot Working
Hot working enhances the overall ductility of the material.
Cold Working
Cold working features of this material is same as that of a moderately tempered austenitic stainless steel. Post-work annealing is recommended to re- attain favorable performance properties.
Aging
Aging of grade 5 Ti-6Al-4V alloy can be performed at 538°C (1000°F) for 4 h, and then air cooled.
