VT machining offers CNC Turning for Grade 9 Titanium (UNS R56320 / Ti-3Al-2.5V), typically supplied annealed or CWSR. Between CP and Gr5 in strength; easily formed into tubing.
CNC Turning Notes for Grade 9 Titanium
On the lathe Grade 9 Titanium needs chip-breaker inserts and constant chip load to avoid long, stringy swarf.
For estimating, a 100 × 100 × 10 mm block of Grade 9 Titanium weighs about 0.45 kg.
