Ti 6Al-4V

UNS #R56400

Ti 6Al-4V offers a combination of high strength, light weight, formability and corrosion resistance which have made it the most commonly used titanium alloy. It is an alpha+beta alloy that is heat treatable to achieve moderate increases in strength and is recommended for use at service temperatures up to approximately 660°F (350°C). Ti 6Al-4V may be considered in any application where a combination of high strength at low to moderate temperatures, light weight and excellent corrosion resistance are required.
