Titanium Grade 5 (6Al-4V) (Ti6Al-4V) is one of the most commonly used Titanium Grades in Aerospace.
Popularized by it’s application on the SR-71 Aircraft (see video), Ti 6Al-4V is significantly stronger than other commercially pure titanium whilst still retaining the same stiffness and thermal properties.
*6Al-4V is manufactured to many different specifications which can be seen below*
