MDS for Grade 9 (3AL-2.5V) Titanium
Primarily the high strength tubing alloy. It is used in a wide variety of products that require light weight, high strength tubing. Available in two conditions, annealed and cold worked stress relieved (cwsr). Annealed has a lower tensile strength than CWSR, but has better forming capabilities. CWSR is stronger, but does not form as well as annealed.
