Grade 2 vs Grade 5 for Titanium Machined Parts
Grade 2 and Grade 5 solve different design problems. Grade 2 is commercially pure titanium; Grade 5 is Ti-6Al-4V. Selection must follow service environment, loading, temperature, source specification and finished-part requirements.
Comparison
| Item | Grade 2 | Grade 5 |
|---|---|---|
| Material family | Commercially pure titanium | Ti-6Al-4V alloy |
| Selection focus | Corrosion resistance and useful ductility | Higher strength-to-weight requirement |
| Source stock | Plate, bar, tube or forging to applicable order | Plate, bar or forging with controlled condition |
| Approval | Design, service and material specification control | |
Machining Is Part of the Process Plan
Cutting speed, tool condition, rigidity, heat control, coolant and chip management must suit the grade, geometry and machine setup. Material grade alone does not define a universal machining recipe.
Corrosion and Galling
Review the full medium, temperature, crevice geometry and mating materials. For sliding interfaces, also define clearance, finish, lubrication or coating and duty cycle.
Compare custom CNC parts, precision bushings and machined discs.
