Grade 5 Titanium is the workhorse of all the titanium grades. Among all the titanium grades, the most commonly used titanium alloy is the Grade 5 titanium alloy (also known as Ti6Al4V, Ti-6Al-4V or Ti 6-4), it is formed with mixing pure titanium with 6% aluminium and 4% vanadium.
Its high strength, lightweight and corrosion resistance enable Titanium Grade 5 to be used in many applications. The most common market is aerospace, medical, marine and chemical processing industries. The alloy is also “age hardenable” by heat treatment to achieve even higher strengths.
