VT machining offers CNC Milling 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 Milling Notes for Grade 9 Titanium
We use high-efficiency toolpaths with constant engagement on Grade 9 Titanium to keep cutting temperature and tool wear under control.
For estimating, a 100 × 100 × 10 mm block of Grade 9 Titanium weighs about 0.45 kg.

How clean are the edges produced by CNC Milling on Grade 9 Titanium?
Machined Grade 9 Titanium edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What surface finish is achievable on Grade 9 Titanium with CNC Milling?
Surface finish on Grade 9 Titanium is controlled to your specification; we confirm the achievable Ra against your callout.
What material thickness or size range suits CNC Milling Grade 9 Titanium?
We machine Grade 9 Titanium across a broad size range; share your part envelope for confirmation.
Why is Grade 9 Titanium a good choice for CNC Milling?
Grade 9 Titanium is high strength-to-weight, biocompatible and corrosion resistant, which makes it well suited to CNC Milling. We tune the process to the alloy so the finished Grade 9 Titanium machining part meets your dimensional and functional requirements.
