Titanium Grade 5 is designated as UNS R56400
Titanium 6Al-4V, Titanium Grade 5 alloy (UNS R56400) is the most widely used titanium grade. Known as the “workhorse” of the titanium alloys, Titanium 6Al-4V or Grade 5 Titanium, is the most commonly used of all titanium alloys. It accounts for 50 percent of total titanium usage the world over.
Titanium Grade 5 is a two phase α+β titanium alloy, with aluminum as the alpha stabilizer and vanadium as the beta stabilizer. This high-strength alloy can be used at cryogenic temperatures to about 800°F (427°C). Titanium 6Al-4V can be used in welded construction at service temperatures of up to 600° F. This alloy offers its high strength at a light weight, useful formability and high corrosion resistance.
Applications include:
compressor blades, discs, and rings for jet engines; airframe and space capsule components; pressure vessels; rocket engine cases; helicopter rotor hubs; fasteners; critical forgings requiring high strength-to-weight ratios.
Product Forms of Titanium Grade 5:
Pipe, tube, sheet, strip, plate, bar, bar, forging stock, wire, ect.
