Overview
6AL-4V is the most widely used Titanium alloy. As an alloyed Grade of Titanium, it is strengthened by the inclusion of roughly 6% Aluminum and 4% Vanadium. 6AL-4V typically comes in the Annealed condition, but it can be strengthened by heat treatment, such as Solution Treating and Aging. The weldability can be poor due to the two-phase microstructure, hardenability is limited and sections over one inch may not develop full properties. Overall, 6AL-4V exhibits high strength, light weight, and corrosion resistance, which make it an excellent choice for applications in aerospace, medical, oil and gas, and marine.
