Grade 2 is commercially pure titanium — softer and more ductile than Grade 5, with corrosion resistance that is if anything better. It is the choice for chemical equipment, heat exchangers and parts that need to be formed as well as machined. It is gummier to cut than Grade 5 and prone to built-up edge, which surprises people who expect pure metal to be easier.

Typical values for the standard condition (Titanium Grade 2 (Commercially Pure)). Heat treatment, temper and product form move these numbers — confirm against the mill certificate for your order.
Excellent corrosion resistance in chemical and marine environments
Much better formability than Grade 5, so formed-then-machined parts are practical
Good weldability
Lower cost than Grade 5
Starting parameters for carbide tooling. These are the shop's working numbers, not brochure values — adjust for machine rigidity, tool geometry and workholding.

| Tooling | Sharp carbide, uncoated |
| Coolant | Flood, well directed |
Softer and gummier than Grade 5, and prone to galling and built-up edge. Keep the feed up and the tool sharp — a dull edge rubs and work-hardens the surface. Chip clearance matters as much as speed.
Cheaper than Grade 5 but still several times aluminum, and cutting speeds remain slow. The economics work when corrosion resistance justifies titanium over stainless.
For the full cost structure — material, programming, setup, cycle time, finishing and inspection — see CNC machining cost per hour, and for how price changes with quantity see machining by production volume.
Not necessarily. It is softer, which sounds easier, but commercially pure titanium is gummier and more prone to built-up edge and galling. Grade 5 cuts more predictably with sharp tooling at conservative speeds. Both are slow compared with steel or aluminum.
Chemical processing equipment, heat exchangers, desalination components, marine fittings, medical and dental hardware where load-bearing strength is not required, and electroplating fixtures. It is the grade you choose for corrosion resistance plus formability rather than strength.
Yes, and it welds well provided the weld is properly shielded from oxygen and nitrogen — titanium reacts with both at elevated temperature, which embrittles the weld. Welding is normally done in an inert atmosphere or with trailing shielding.
It is one of the best materials for seawater service, with essentially no measurable corrosion rate in natural seawater at ambient temperature. That is why it appears in desalination and marine hardware. The limitation is cost and machining difficulty, not corrosion.
