Titanium Alloy

Aerospace Engineering

Titanium alloys are titanium blended with other elements, most often aluminum and vanadium, to raise strength well beyond commercially pure titanium while keeping its low density and corrosion resistance. Ti-6Al-4V, roughly six percent aluminum and four percent vanadium, is the most widely used titanium alloy; metallurgist Stanley Abkowitz pioneered it in the early 1950s at the U.S. Army's Watertown Arsenal Laboratory, and it entered wide service on aircraft such as the U-2 reconnaissance plane. Its combination of high specific strength, weldability and biocompatibility has made it the standard titanium alloy for aerospace airframes and engines, biomedical implants and high-performance sporting equipment.
